Consistently shirtless.
When I was going to sleep earlier for my seven pm nap, I could feel a cutoff point from regular-consciousness to the dream-like state of falling asleep.
It was awesome. I was like: head on pillow, think about various insane things(code, books, universe, spray-painting shoes), then it felt like I seperated from my body, but only half-way. Like I was floating slightly above myself, but being in myself at the same time.
I like to hope that this is my brain creating a palpable difference between awake time and nap time. That would be awesome, because I have huge problems getting to sleep for my naps sometimes.
