ok last night i went to bed after relaxing for awhile i put on headphones with ocean wave sounds playing to relax i was there laying for a good 30 min at least my arms went numb and my legs were tingling a bit and i started to see colors and then i felt a big rushing feeling like i was being accelerated downward and i saw a flash in my eyes and i layed there not moving wondering if i was asleep or awake i didnt want to move and i didnt want to open my eyes to waste all that time i spent getting relaxed and SP so i just layed there relaxed and in 5 min i went into a normal dream. was it possible that that was a false awakening? could i have been asleep?
