I don't think I understand the (technical) question. When your computer goes to sleep, it uses a tiny amount of current to keep the RAM in "self-refresh mode", to stop the RAM decaying, and then turns off the CPU.

Given that the CPU has no power, there is no meaningful analogy to dreaming in any sense.

Agreed. However, if we consider a computer with complex AI capability(Jarvis), can it dream. Dream is kind of a state for us humans, similarly, If Jarvis goes to sleep what we can except, does it projects random thoughts and ideas. Can it dream about all those crazy ideas like humans do. It does kind of open up the possibilities of making a machine think more than he can achieve.
