Is this sleep paralysis?

I know this is really weird. I was laying in bed, I think I woke up from a dream? And I was bit on the neck, d, and then choked. I was trying to scream, but I couldn't. I even tried banging on the wall, because my roommates are in the room next to me.. couldn't move. I was obviously terrified and thought I was losing my $%@ing mind. I came to the conclusion of sleep paralysis? These sorts of episodes happened to me as a teenager(early to mid teens). And I don't know if it matters, but I was ually abused as a child. Are those kind of vivid hallucinations possible? The dream I had before the episode was of a woman and I was about to kiss her.. and thats all I remember from it. I also remember screaming at something/someone directly after the episode to get out of my body and felt like I was shooken kind of harshly. Really spooky! Sounds crazy I know!!
