Well, I learned years ago in my early 20s that we only require small increments of sleep in order to “re-up”. We can be hard core tired and we start drifting in and out of sleep. Our brains are grabbing at whatever it can get. It’s reached what it needs to work properly so BAM, wide awake again. I watched this thing on sleeping and people that believe they haven’t slept in months due to insomnia but in fact the brain actually turns itself on and off while their eyes are open etc. we don’t even realize it I guess. I’m just sharing what I remember about it and I’m not exactly right I’m sure.
