In brief: Gaba and glutamate

Sleep is affected by dysregulation of gaba and glutamate receptors, in a person who is withdrawing glutamate is reactivated.
Glutamate is excitatory which yields to hallucinations etc thru not only glutamate but other receptors as well . Downregluation of gaba also affects the sleep cycle.

In brief: Several ways

Alcohol can produce sleep by its sedative effect, but it wears off quickly, causing a "rebound" with increased wakefulness a few hours later. While it increases deep sleep (just as most sleeping pills do), it reduces rem sleep, which is when we dream. If people drink a lot to stay asleep, they may get "rem rebound" which can cause daytime awake dreams, similar to hallucinations.
