If it makes you feel any better i had one last nite, i was WILDing and my legs felt like i had bricks on them, like a big slab of concrete then my hands and arms where numb, i kept getting a shooting pain in my left arm and my back, on the right side, i then stopped the (humming sound you use to keep yourself awake) and i noticed i stopped, but i didnt intend to stop, so i was like wat the hell? so i tryed to carry on, and i closed my eyes and i could see my brain shape on my eye lids, im sure this was a hpyagogic illusion, not to sure but whatever it was got my heart racing a bit, after a while i managed to start humming again then my body fell asleep and i once again stopped, i then felt i was dreaming, so i looked at my phone cause the alarm went off, and it said 4:01am then i looked again and it was 4:00am so i thought Hmmm a minute difference doesnt sound to dreamy so i gave up and went to sleep lol
