I had a nap on the couch (it was 3 in the afternoon) and was lying there and suddenly I felt a large falling sensation before waking up. Then I decided to have a nap in bed so I went to bed so I lyed there for 15 mins before feeling my hand suddenly tighten and a flashing vision this scarred the sh** out of me And I wiggled my fingers( in case it was paralysis) and threw myself up.
