A new theory of dreams

I am not a sleep specialist, but I do know that getting enough sleep is a very important part to healing the mind from traumatic experiences. I would speculate that we have inherent qualities within us, a natural resiliency and 'human' tendencies (interpret as you wish) that, if given REM sleep can test out the damaged schemas of the non-REM sleep, discarding them over a period of time until we cull the maladaptive schemas.

Interesting video.
