Dream About Night Terror Outer Body Experience

I went to bed, and I fell asleep, obviously, and then I must have started dreaming or whatever, and so there I was, dreaming, but I'm awake now, but I'm in the same bedroom where I was asleep, and now it's like I am up in the corner of the room, looking down on myself as I sleep, and so there I was, a fly on the wall, but me, looking down on myself, I'm sleeping on my bed. Okay, so then all of a sudden, I look over to the, I guess my right, and I look down, and I could see this mass, this dark mass, that forming, kind of coming up under the door and up all, like, onto the wall, and it was creeping, like, you know, and it was making its way slowly to where I was laying, and it came up onto the bed. This is all, like, taking a while, and it comes over me in my sleep, as I'm watching myself sleep, like, you know, and as I was sleeping, all of a sudden, I can see this black mass start going into, like, as I'm breathing, it's like I'm breathing it in, and then, and then, and then, I'm watching this happen, but then all of a sudden, I wake up from my dream, night terror, whatever you want to call it, and I was choking, I woke up choking, and I sat, I was sitting up exactly how I had seen myself in this dream, and it was so weird, it was so weird, I don't know, like, I, like, it made me cry, and I don't even know if, like, I don't know if that was even a dream, or if, if that is, if there's paranormal, or I had an outer body experience, I don't know, so maybe you can decipher it, but at that point, I had had night terrors for, like, three, four years in a row, anytime, anytime I fell asleep, I would have terror, terror, it was always terrors, so, I don't know, maybe you can help me analyze that one, it was the freakiest thing that ever happened to me, and, and it was in my dream, I guess.
