i very well could be suffering from mild narcolepsy (not to mention acute hypochondriacitis). i can't manage to surpass a posture of 50 degrees without falling deep down a rabbit hole and straight into REM sleep. it's a blessing and a curse. i never need sleep meds, but i need a foghorn of an alarm clock. i can and have fallen asleep anywhere, anytime. you name it. this has been happening all of my life. when i was 3, my dad took me horseback riding. He put me on his shoulders (hey, it was the 80s! safety was no thang back then) and i fell asleep, on him, him on the horse. when i was eighteen, i fell asleep driving once. i had made it about 15 miles when i came to, crashing into the car infront of me. i had no recollection of driving from mesa to tempe. scary. with that said, it's my bedtime.
