Whispering in someone's ear while they sleep has been a topic of fascination for many, with some believing it to be a form of bedtime brainwashing. While it may seem like a myth or a trope, there is some scientific evidence to suggest that our brains can process and hide memories of what we hear while asleep. A study by PSL Research University in Paris found that participants' brains showed electrical activity in response to words heard during sleep, indicating that their minds were responding and remembering these words, even if they couldn't consciously recall them. This has led to speculation about the potential for learning while sleeping and influencing dreams or thoughts. Some people have shared their experiences online, reporting whispers that range from comforting messages to unsettling ones. So, does whispering in someone's ear while they sleep work? It might, but the ethics of experimenting with another person's subconscious are questionable.

What You'll Learn
People report hearing whispers in their ear while sleeping
Many people have reported hearing whispers in their ear while sleeping. Some of these experiences are shared by couples, where both partners hear the same whispers. These whispers are often in the form of a voice that calls out the sleeper's name, or says simple phrases like "hello" or "it'll be OK".
While the phenomenon of hearing whispers while asleep is not uncommon, the scientific explanation for it is still developing. A study by researchers at PSL Research University in Paris found that the brain hides memories of things heard while asleep, processing them in a different way to memories of things heard while awake. The study found that participants were able to identify words they had heard while sleeping, and their EEG readings when presented with these words matched those of people remembering things. This suggests that the brain was responding to and remembering the words, even if the conscious mind could not access these memories.
The study of memory formation during sleep is still in its early stages, and further research is needed to replicate the findings in a range of populations. However, the potential to help people learn while sleeping is an exciting prospect.
In the meantime, those who experience hearing whispers while sleeping may find comfort in knowing that they are not alone in this phenomenon. While it can be a frightening experience, it is important to remember that there are scientific explanations for these occurrences, and that the brain is simply processing and hiding these memories in a different way to how it usually operates.

Brain hides memories of things heard while asleep
While you sleep, your brain may still be able to process sounds, including whispers, and hide the memories of these sounds from your conscious mind. This phenomenon has been observed in a study where researchers tested the sleep memories of 22 French speakers, aged 20 to 28, using EEG (electroencephalogram) to measure electrical activity in the brain. The researchers played a mix of real French words and fake French-sounding words to the subjects while they were awake and instructed them to press a button to distinguish between the two. Later, the subjects performed the same task while falling asleep. The researchers found that the subjects could not consciously distinguish between words they had heard while asleep and words they had never heard before. However, when they had heard a word while sleeping, they were not confident in their answers when asked about it later. This suggests that their brains had faint recollections of the words, even if they could not consciously remember them. Furthermore, when the subjects did successfully identify a word heard while sleeping, they were very confident in their answers, and their EEG readings matched those of people remembering things, indicating that their brains were responding to and remembering the words heard while sleeping.
These findings offer evidence for the idea in cognitive science that there are two types of memory: explicit episodic memory (remembering) and an implicit sense of familiarity (knowing). While the brain turns off episodic memory during sleep, possibly to organize the day's episodic memories, it continues to form implicit knowledge memories. This hidden mechanism could be refined to help people learn while sleeping. For example, scientists have been able to specifically target certain memories and reactivate or strengthen them using auditory cues, suggesting that we may be able to induce brain waves that enable learning during sleep.
However, it is important to note that the study on French speakers had a small, homogeneous sample, and further research is needed to replicate the results in different populations. Additionally, while sleep is crucial for learning and memory formation, the exact mechanisms behind this process are still being explored. Nevertheless, studies have shown that non-rapid eye movement (non-REM) sleep, or dreamless sleep, is vital for consolidating memories, and sleep spindles, or spikes in brain activity during the second stage of non-REM sleep, play a key role in this process.
While the idea of whispering in someone's ear while they sleep to impart knowledge or influence their behavior may seem intriguing, it is important to respect their privacy and consent. The current scientific understanding of sleep and memory suggests that simply whispering information may not be enough to ensure retention, and more research is needed to fully comprehend the complex dynamics of sleep, memory, and learning.

Some believe whispering can influence dreams or thoughts
While the idea of whispering in someone's ear while they sleep to influence their dreams or thoughts remains largely within the realm of fiction and tropes, there may be some scientific basis to it. Some people anecdotally report hearing whispers in their ear while sleeping, which can be unnerving and even traumatizing. These experiences are sometimes associated with sleep paralysis or religious beliefs.
Research suggests that our brains can process and respond to words heard while sleeping, even if we are not consciously aware of them upon waking. A study conducted by PSL Research University in Paris found that participants' brains showed electrical activity in response to words played while they slept, indicating some level of memory formation. This supports the idea that our brains continue to form implicit knowledge memories during sleep, even if we cannot consciously access those memories.
Building on this concept, it is theoretically possible that whispering in someone's ear while they sleep could influence their thoughts or dreams. However, it is important to note that the content of the whisper would likely need to be simple and repetitive to have any chance of being processed and remembered by the sleeping person. Additionally, individual factors such as sleep stage, brain activity, and personal receptiveness to suggestion could also play a role in the effectiveness of whispering as a means of influencing dreams or thoughts.
In popular culture, the idea of "bedtime brainwashing" is often portrayed as a means of influencing a sleeper's dreams or thoughts. This trope is seen in various media, including comic strips, where characters whisper suggestions or commands into the ears of sleeping individuals to manipulate their behavior or dreams. While these depictions are often exaggerated for comedic or narrative effect, they tap into the underlying notion that our subconscious minds may be susceptible to external influences while we sleep.
Overall, while there is some scientific evidence suggesting that our brains can process information during sleep, the extent and nature of this process are not fully understood. The idea of whispering to influence dreams or thoughts remains largely speculative, and further research is needed to determine the validity and ethical implications of such practices.

It may be possible to help people learn while sleeping
It may be possible to influence a person's dreams, thoughts, or behaviour by whispering in their ear while they sleep. This is a common trope in media, known as "bedtime brainwashing", and is often used for comedic or troubling effect. For example, in one comic strip, a character whispers to their sleeping father that he will buy them a Trans-Am, and the next day, the father presents them with a canned ham.
However, there may be some scientific basis to the idea of influencing people while they sleep. A study by PSL Research University in Paris found that the brain does process information heard while asleep, forming implicit knowledge memories. The study tested participants' sleep memories by playing a mix of real and fake French words while they slept, and then testing their recall of these words when they woke up. While participants could not consciously remember the words, their EEG readings when presented with words heard in their sleep matched those of people remembering things. This suggests that their brains had responded to and remembered the words on some level.
Further research could potentially build on these findings to help people learn while sleeping. However, it is important to note that the study had a small, homogeneous sample, and would need to be replicated with a range of populations to increase confidence in its conclusions.
While the idea of learning while sleeping is intriguing, it is important to consider the ethical implications of influencing someone's thoughts or behaviour without their knowledge or consent.

Some say whispering can influence a sleeper's behaviour
It is said that whispering in someone's ear while they sleep can indeed influence their behaviour. This concept, known as "bedtime brainwashing", has been explored in various media, including comic strips and TV shows. The idea is that the whispering character attempts to influence the sleeper's dreams, thoughts, or behaviour when they wake up. For example, by saying something pleasant and reassuring or chanting a command or mantra.
In a study conducted by researchers from PSL Research University in Paris, it was found that our brains do process information heard while asleep, even if we are not consciously aware of it. The study involved 22 French speakers who were played a mix of real and fake French words while their brain activity was measured using EEG. Results showed that their brains responded to the words, indicating some level of memory formation, even during sleep.
While the idea of bedtime brainwashing may seem far-fetched, there are anecdotal reports of people hearing whispers while asleep, which influenced their dreams or left them feeling disturbed. Some people have shared experiences of hearing whispers that caused them to have frightening dreams or feel anxious.
However, it's important to note that the effectiveness of whispering in influencing a sleeper's behaviour may vary. Some people might start dreaming about what they hear, while others might not hear it at all or wake up. Additionally, the sleeper's mental state and the content of the whisper could also play a role in how they are influenced.
So, while whispering in someone's ear while they sleep may not guarantee a specific outcome, it is possible that it could have some impact on their subconscious and, consequently, their behaviour.

Frequently asked questions
It depends on what you mean by "work." Research suggests that the brain turns off episodic memory while asleep, but it continues to form implicit knowledge memories. So, while the sleeper might not remember what you whispered, their brain will turn those words over somewhere deep in their mind.
Maybe. Some people report dreaming about noises they heard in their sleep, like a phone beeping. However, others do not remember their dreams, or they wake up.
It's possible. This is a common trope in media called "bedtime brainwashing." In theory, you could whisper something pleasant to calm or delight the sleeper, or you could attempt to trouble their dreams with worries.
Maybe, but it's unlikely. While some researchers suggest that science could figure out how to help people learn in their sleep, this theory has not been tested extensively.
It could be. Some people report finding it traumatizing or frightening.
