Pressing Down

This is my first time writing here, but I need help.

I am sorry for my english,it's not my first language.

I live with my mom,dad,and brother in a small apartment.

About a year ago I woke up to my chest being pressed to the bed. I was sleeping on my chest, but something was pressing my back down. When I opened my eyes it stopped and I could move. When I closed them and when I was almost asleep it started again, but I still could move.

I thought that that was maybe my imagination, but then every time I started to fall asleep I would hear whispering. At first I was a bit scared but not too much. Almost every other night I would wake up due to feeling that one of my body parts is being pressed down. When I feel that pressing, I don't feel the hand or the tingling, I feel it like it's some like of force pressing me down. That little night sessions would last about 3-4 days in a week, and the stop for a 2-3 weeks, and then come back. Every time it's different.

I also noticed every time that pressing would happen, I wake up around 1am laying on my back, then I turn on my side, and then I wake up around 3am on my stomach feeling the pressing down. I wasn't scared after the second time happening, I knew if I feel scared that it would do me no good, but once when I woke up, I wasn't scared but that presence, it was like it was forcing me to be scared. In my mind I wasn't scared, but I could feel forced feeling of scared in my chest, and it was weird.

A few weeks back it was a very light pressing and then it stopped but this night it was the most aggressive one. I woke up this time around 3am on my back, I knew what was happening but I thought that it would be light pressing. I turned on my side and then I woke up due to the feeling of jumping on me? I first felt it on my wrists, then my butt (sorry), then I felt it again on my wrists, it was like somebody was jumping on me. I opened my eyes and ofcourse It was nothing, and I decided to stay awake, but I felt light pressing on my legs.

When I was again almost falling asleep, I felt pressing on my back and heard whispering again. It was around 4 am, so I turned on my back, still in dream like state and whispered back who is it. I didn't think that that it would reply but they whispered back so aggressive that I couldn't understand. I try to ask what is it that they want but the pressing started again, and the only thing I could understand is destroy, and when I wanted to open my eyes I couldn't! I could move, and talk but I could't open my eyes. Soon it stopped, I was relieved and I just passed out.

When I woke up, I was feeling that scared feeling, and I still am in my chest, but the thing is I am not scared. Every time that it would happened I wake up feeling exhausted...

Can anybody tell me what is going on?
