Pretty much every time i take a nap or try going to sleep while laying on my stomach, i wake up exactly 11 minutes after laying down. The dream already is fully formed around me (for example today while taking a nap i was already playing my guitar in my dream with full detail) and then all of a sudden i just feel this force and i get sucked out of the dream and become fully conscious, and my body has this buzz like when you wake up from a LD and lay still. It started maybe a month or two ago so i was wondering if this happens to anyone else when sleeping in a certain position?
