While we're here, can someone explain how a "dream within a dream" works in Inception ? Presumably someone has to "fall asleep" inside their (or someone else's) dream and go into a dream state again on another level so to speak. The only way I can see the brain implementing that is to dream of its own state so completely that it can run itself as a virtual machine, and fall asleep inside that VM. I haven't read the code, but I doubt the C implementation includes a VM that can run inside itself, Smalltalk-style.
