This experience happened to me just last night; it was around 11:45 pm and I was asleep when for no reason I woke up and at that very same instance I realised I was having trouble breathing. I was grasping for air and the best I could do was take fast breaths of air, I didn't think much about it that very same second until I tried getting up from bed. I tried moving my arms but they felt like they were being restrained down by something very heavy, I struggled like this for a couple of seconds. I moved my right arm up and just when I thought I had it freed it was pushed back down to the side of my body again. At this moment I realised I wasn't getting away, the best I could do was move my head to the side and try to scream for help but I wasn't able to talk nothing was coming out of my mouth. I moved my head back up and just as I did this I thought I saw a dark shadow crawling up my wall into the ceiling (this I'm not so sure of), but just I "thought" I saw this, there was sort of a laugh near my ear that seemed to be echoing and it was followed by a ringing noise, this noise I can't explain it's just something I've never heard before. This noise was there for a minute or two and as it started to fade away the pressure that I felt holding my whole body down faded away with it. I felt this pressure lift from my chest first then my arms and finally the rest of my body, the first thing I did after this is I took a deep breath and just felt relieved.
I laid in bed for a couple of minutes after this and kept hearing a buzzing noise in the room, but that didn't bother me as much as the thought of feeling helpless, I kept thinking and looking for an explanation in my head but I could not think of anything logical. The rest of the night I tried sleeping but felt more secure if I slept on the side of my body instead of on my back, and finally fell back asleep.
This morning I woke up to find that my right wrist is bruised and just to assure myself that I wasn't just seeing things I asked my co-worker at work to look at my wrist and tell me what she saw, and right away she asked why my wrist was bruised. Up to this moment I'm still trying to find an answer to my many questions about what happened.
Does anyone have an idea of what this might be? Just for information I don't do witchcraft or whatever it might be called, and I don't practice religion. In the past I have had several other experiences that I can't explain and it's been happening since I was a small boy, I sometimes sense things no matter where I might be; but this experience is the closest I have gotten to being harmed. If anyone can help please do... Thank you
