Glad to see others power nap also, I thought I was just weird.

My routine is at about 1:30 slouch in my chair leaning back with my hands atop my head with fingers inter locked.

Whats strange is that I don't really goto sleep. I can hear everything going on around me but my mind is just totally blank and not focused on anything.

I stay like this for around 15-20 min then snap out of it fully refreshed!
