Clearly the brain *did* evolve to dream, although we don't really understand the evolutionary advantage of dreaming, or for that matter sleeping. But that is beside the point: the question is whether interaction with an external environment is necessary for consciousness, and I think dreaming is one situation which shows that it is not. (To be fair, one could argue that dreaming does involve environmental input in that at the very least there is proprioceptive feedback from the rapid eye movements, and there is no dreaming during non-REM sleep. However, I think that is just a technical detail, as it is easy enough to imagine a brain dreaming without this input, or with the input provided by self-exciting neurons.)
