I have had sleep paralysis attacks multiple times in my 20's, on occasion I still do, if I lay on my back and if I sleep on the couch. It begins with a humming, I picture a little girl in a blue dress like a small Alice in Wonderland. When I hear that humming I become terrified, it's like certain endorphins are released and I can't help but become afraid. There is a hooded shadow in the corner of the room, it makes me look at it. I have tried to avert my gaze, but my head is pulled in its direction. Once I thought to attack it, I happened to have a saber next to my couch. I got it, got up and walked over to the shadow and raised the saber, then blinked and realized I hadn't moved. It's like it let me hallucinate this in order to say, 'Stop fighting, this will do you no good.' It sucks the energy from me, the fear produces certain endorphines, and it's like this shadow feeds on them. I feel very drained afterwords. I researched the esoteric and especially the left-handed path back then, and I feel this thing was drawn to me because of that. If you research sleep paralysis, it says that it happens mostly in your 20's and that it could well begin in your teens, but by the time you are 30, the attacks will lessen and eventually stop. Still, I never looked forward to these attacks, I was wide awake and not hallucinating. To me, this happened, this was reality, and so it holds true for me.
