I've experienced sleep paralysis a few times. This experience was quite different. I was about 15 years old and I was up late on a school night. I was dreading going to bed... I was looking for other stuff to do. I was avoiding my room altogether but I didn't know why.
Finally, trying to be responsible so I could get up for school in the morning, I dragged my feet to my room. I readied for sleep still very uneasy. I jumped into my bed and as I laid my head down on my pillow, the memory of the experience I had the previous night came flooding back into me. Frightened, I jumped back out of my bed and ran upstairs to be with my parents and tell them what happened to me.
Here is what happened. It was in the middle of the night. I was awakened by something gripping me very tightly. I could not see anything in the room because it was dark and I could not speak. There was an intense buzzing noise in my ear as though I was tightly clenching my jaw. I tried to cry out but no noise came out. I could sense that I was floating in the air with my back arched backwards and I was facing up with my arms hanging down. I was taught from a small age that I can command evil spirits to leave. I could not do so because I could not speak. I tried with all my might but could not get anything out. After struggling like this for what seemed like only 15 seconds, I gave up the will to struggle. I don't remember anything after that and didn't remember the experience until the following night.
It has always scared me that I gave up the will to struggle and then don't remember anything after that. I've had reoccurring nightmares about the experience that have faded over the past 20 years until now I can't remember the last nightmare about it I had was.
My regular episodes of sleep paralysis are simply a buzzing noise in my ear and not being able to move or talk. Out of curiosity I've even tried hard to open my eyes. These episodes don't scare me and I usually fall back asleep completely in a few seconds. I understand that it could have entirely been sleep paralysis. But I feel strongly that something attacked me while I was in this vulnerable state.
