What You'll Learn
Superman can sleep, but does he need to?
Superman's powers come from Earth's yellow sun, which supercharges him. This means that he does not need to eat, drink, sleep or breathe. However, before his powers had fully matured, he did need to do these things, so it is possible that he is simply in the habit of sleeping. Additionally, it may be that Kryptonians have evolved to need sleep, and so Superman still sleeps despite not needing to.
It is also worth noting that sleep deprivation can drive Kryptonians to dangerous mania. In one instance, Supergirl is driven to attempt to kill Superman due to a lack of sleep. Therefore, while Superman may not need to sleep for his own health, he does need to sleep for the health of those around him.

Superman's dreams
Superman can sleep, and he does so frequently. In *Superman #9*, Clark Kent zones out during a family discussion, and then apologises by saying he forgot to sleep. In *JLA #22*, Superman is affected by a 'sleeping plague', further demonstrating his physical capacity to fall asleep.
Superman does not need to eat, drink, sleep, or breathe. However, before his powers fully matured, he did. So, it is partly that he is in the habit of doing it, and partly that he likes doing it.
Superman may be able to survive by replacing sleep with sunlight, but unless he gets at least a little sleep once a week, all those around him are in danger. For example, in one instance, Superman's cousin, Supergirl, is driven to dangerous mania by her sleep deprivation, attempting to kill Superman despite their close relationship.

Superman's sleep deprivation
Superman can sleep, but he does not need to. In JLA #22 by Grant Morrison, John Dell, and Howard Porter, Superman is affected by a "sleeping plague", demonstrating that he has the physical capacity to fall asleep, even when he's at full power. However, this is directed by an outside force, so it is not clear whether Superman needs to sleep. In Sandman #71, Superman, Batman, and the Martian Manhunter are pictured as guests at the wake for Dream of the Endless, an event attended by every being capable of dreaming. This suggests that Superman can dream, and therefore sleeps.
In Superman #9, Clark Kent zones out during a family discussion and then, by way of apology, shares Batman's theory on the matter: "I forgot to [sleep]". This suggests that Superman does sleep, but it is not clear whether he needs to.
Superman may be able to physically survive by replacing sleep with sunlight, but unless he gets at least a little sleep once a week, all those around him are in danger. For this reason, it can be argued that Superman does need sleep, but it is for the health of those around him rather than his own.
Before his powers had fully matured, Superman did need to sleep. So, it's partly that he is in the habit of doing it and partly that he likes doing it.

Kryptonians may have evolved to need sleep, but Superman is being supercharged by Earth's yellow sun, so what does he actually gain from sleeping? If nothing, what governs when he sleeps, wakes and dreams?
