Sleep paralysis

I had a terrifying sleep paralysis experience a few days ago. I'd never even heard of it before this happened. I sleep alone, so I was terrified to go sleep last night. I knew that it happened to me the other night as soon as I started falling asleep, so I was lying awake for 2 hours last night before falling asleep. I am so scared that the man is going to come back! He was literally so real, he was standing right next to my bed, I couldn't believe what I was seeing, I was lying there paralyzed, staring at him for a long time, he was just staring back at me. I reached out to check if he was real, and I could feel his pant leg. He was wearing jeans and I could feel myself being dragged across the carpet of my bedroom, I could feel the carpet once he had grabbed me by the neck, I could also feel the window ledge as he was trying to push me out of it....I am actually thinking of adopting a pet for some company..😥
