Dunno about you, but when I sleep during the day, (I’m usually a normal night sleeper and don’t have a weird schedule like EMTs etc.) which I don’t do often, I can never really manage to “sleep.”
This “day sleep” that I encounter–remember that this is not a daily habit but maybe once every two months–is not really a sleep but just one dream “extravaganza.” I have extraordinary dreams, sometimes populated by amazing amounts of people, and sometimes everyone is nice but sometimes everyone is not nice. Sometimes people whom I have not thought of for two decades surface in these dreams.
Why is this day sleep so different from my normal nightly oblivion? It has nothing to do with light coming in the window or noise, since I wear earplugs and the blinds pretty much block out all light.
My wife has also reported this “pseudo-sleep.” Needless to say, I am not a Power Napper.
What is going on in the vast network of dendrites and neurons? What exercise is my brain trying to have?
