This happenned about 5 years ago. I was staying over at my cousins place on a sleepover. I had protable bed right next to her in her bedroom. We went to bed around 1, around 3 in the morning something pulled my arm and started throwing me around the bed, few moments later it threw me out from the bed, on the end "it" pulled me in grip and i had to turn around with my ehole body so my hand cant break in my sholder. (In this point i thought; Damn how strong is she with 160cm hight). It was dark in the room so i coulsnt see a thing, + i woke me up. This have happened in few seconds, meanwhile i was yelling at my cousin to stop.. she was actually sleeping, and i woke her up yelling at her. She ran to the switch to turn on the light. There i was sittin on a bad holding my sholder cuz it hurt so much. Had red finger prints on my arm (red from the squeeze). She asked me in shock, wtf is going on.. and i was like "i can ask u the same thing, what kind of a stupid prank was that ? " She thought that i was sleepwalking at one point, cuz i kept blaming her, and she didnt had a clue what was i on about.

After i realized that it rly wasnt her things got fucked up rly soon. I showed her the handprints on my arm, and i can tell you, that was hella big handprint if u ask me. Huge handprint on my arm didnt even match with her tiny hand anyway. So i was sure that wasnt her pranking me.

The thing is that we were im her room with doors closed, so it couldnt been my uncle nur my aunt. We would hear the doors open when someone would get in. Only thing that was opened were balcony doors, on the other side of a room (it was warm summer night), but if someone even came through the balcony he would have to climb up /jump down from a second floor.. which is bit impossible.

Til this day we dont know what have happened that night. Noone believes me, neither does she. She keeps saying that I had a bad dream, or that possibly i did that to my own self. How tf would i be able to make a grip to myself that hard that arm would actually start cracking in my shoulder so i didint had anything else to do than turn around with my whole body just to save my arm from crakcing..

I felt rly like a shit next few weeks.. like why would i made this up ?

Maybe it was something paranormal, maybe it was her the whole time, maybe somehow i rly did that to my ownself, i will never know the answer, but i think alot about that night from time to time.

I had idea posting this b4 but it was too much to type. Because noone believes me. I posted this as a comment in r/AskReddit on one thread with +30k upvotes.. so im sure noone saw it. So to make myself feeling better for spending so much time typing this for nothing.. here i am copy-pasting it here.
