So boners signify REM sleep?
I downloaded an online copy of Exploring the World of Lucid Dreaming and came upon an interesting section discussing physically why and dream and what is actually going on while we do. Here is a quote:
The transition from quiet to active sleep is quite dramatic. During the active sleep phase, commonly called rapid eye movement or REM sleep, your eyes move rapidly about, much as they would if you were awake. Your breathing becomes quick and irregular, your brain burns as much fuel as it does when you’re awake, and you dream vividly. If you’re male, you probably will have an erection; if you’re female, increased vaginal blood flow.
Does that mean that a sure way of knowing if I woke up during REM sleep is to check my pants? Or does morning wood occur during all phases of sleep?
Then the movie "Inception" is all wrong!?
Given this fact, everyone in the movie "Inception" should have been fully erect throughout every scene! Someone didn't do their research! :banana:
