over the past couple nights when ive been drifting off to sleep, ive noticed that my brain goes through this problem solving "protocol".I'll be thinking about something while im falling asleep, and my mind automatically goes through a bunch of scenarios regarding that thought. and everytime, it seems my brain is trying to "solve" whatever im thinking about. keep in mind, this is all happening while im falling asleep, so i have no control over it. the only reason i know im doing this is because ive rolled around in my bed while my head was doing this, then i realized it was happening. it was like i caught my brain thinking on its own.
Is this happening because my brain has no stimuli to comprehend, so its problem solving skills are honed?
Does anyone know anything about this? does this sort of thing happen to anyone else?
thanks for reading
