Violent Ghost Attack in Dream

This whole experience seemed 100% real as it was happening in my mind, I assume it must have been a dream but it was, by far and away, the most realistic dream/nightmare I have encountered.

I, what I thought was, awoke from a deep sleep, with trouble breathing, as though something had its hands wrapped around my neck, I opened my eyes to see this person, who was under my covers, sitting knees first down on top of my chest choking my throat, with their knees holding my arms down. I couldn't see a face straight away. I tried screaming for help from my wife who was working on the computer in the adjoining room, but was unable to mutter much more than a faint murmur, due to the being's hands wrapped around my throat. After several minutes of trying to fight this being off my body, I finally got a hand free to knock on the wall to attract my wife to come for help, where I was able to somewhat fight this being off my body until my wife came in and I was then able to see this beings face for the first time, looked like a blond female's face who had been drowned. My wife finally helped me get this being off me and as I got up to hug her and turned around the being was gone.

I got my wife to come to bed with me and we held each other close, and finally slowly dozing off again, I realized that this being was back and that it was not my wife. I felt a surge of pressure being applied to my body by this being, as it once again tried to sit down on top of my chest, while I was fighting this being, I assume I passed out. What seemed to be about 5 minutes later, I physically woke up, for real, this time, threw my covers off, turned on the light and headed straight for my wife in the next room. I told her about my experience and she could see I was quite shaken up about it, I asked her about things like did she hear me scream? Did she come in to help me? To which she didn't. All I could put this down to was a dream, but after reading similar stories on the net, wonder if it could be more of a sleep paralysis syndrome? I take antihistamines before sleep, but have done so for well over 10 years now, with no previous occurrence of this at all. I have had what I believe contact with the paranormal before, although previous times have been when I was well and truly awake. I have had about a month ago what I believe to be a real ghost "good" dream with my deceased grandfather.


Can ghosts visit in dreams? I didn't think it was possible? This experience has freaked me completely, and hope there have been others that have experienced something similar in the past?
