I'm not sure if its something paranormal or something scientifically verified.

Lately I've been doing something. It's a bit hard to explain. It's sort of like meditation but not. What I do is close my eyes for a few seconds, tilt my head back a little and try to invoke/bring up a feeling I frequently feel when I'm sleeping.

I'm assuming it's serotonin because a deep peace and pleasurable feeling washes over me. My thoughts also get a little cloudy. It feels so strong I swear it's almost spiritual.

It might have something to do with being sleep deprived. I dunno.
