I never knew there is a sex and sleep related disorder: sexsomnia. It means that people that have this disease are walking around in their sleep and having sex. Also, it seems that one guy was acquitted of rape because of such disorder. I still can’t believe such disease can exist.
Also, what is sleep drunkenness? sleep drunkenness or severe sleep inertia is when you wake up suddenly and you’re extremely disoriented. You won’t be able to make heads or tails of your life for 15 minutes and you may go to work in your underpants if you don’t wait long enough to be fully awake.
You experience sleep drunkenness when you are awoken up in the REM stage of your sleep, the stage in which you sleep the deepest sleep.
