What really happens when someone drinks alcohol to the point of blacking out?

What forces are at work when someone loses their self control, acts out of character, and wakes up the next day with no memory of their actions?

AfterLife: The Adventures of a Lost Soul, is inspired by real life events, William Peter Blatty's The Exorcist, and the dynamics of demonic possession. In this supernatural occult thriller, Steve Hanson confronts satanic worshipers who contribute to his death in a grisly motorcycle accident. When he wakes up outside his body in spirit form he is met by other spirits, among them his deceased girlfriend who teach him how to "borrow" the bodies of mortals so he can re-experience physical sensations to learn how to reincarnate into the physical world to complete his karma.

Freed from the three dimensional limitations of space and time, Steve travels through the ethereal worlds of spirit, dreaming, and other fluid states of consciousness to discover that things are never what they appear to be on the surface.
