I think that the correct answer is no. Current computers don't dream, they are like in cryogenic suspension, totally frozen. There is no activity. (Actually there is a difference between "sleep" and "hibernation" mode, but neither are dreaming states.)

Nobody know why we sleep. There are a lot of theories that go from unsupported to bushtit.

Anyway, my favorite theory is from Crick and Mitchison. It's probably wrong, but it's so nice that it deserve to be true at lest in an alien specie or something. It would be a sad universe if this theory were totally false. But, being nice is not enough to make it correct :(.

Someone made a special kind of neural network where this kind of "dreams" are useful for learning, but this networks are totally different from the networks in the brain.
