Haha nice, and pretty much spot on, nearly everyone has tried to stay “asleep enough” to go to toilet and then back to bed right? We have that ability all the time, presumably because other humans can guard us, some other mammals are the reverse.
Most areas of the brain will change its output base on “sleep juice ” we really have several types and locations for cognition, sleep makes them all dopey.
Personally, I think sleep makes all these areas come back into timing.
Read “why do we sleep”, etc. Still pretty controversial.
