My sleep paralysis experience:
There I was laying on my bed peacefully sleeping. It was probably around 1:45am-1:49am. Then all of a sudden I felt like I was wake. I looked around me and I was in my room and I was in my sleeping position. I tried to move my arm but I couldn't. All of a sudden the air felt cold, as if I was outside on a breezy day. Then I felt as if something or someone was on my chest.
I looked at the corner of my eye and I see small children. But they didn't look like ordinary children. Then I heard it. A train. I tried to open my mouth to scream but I was unable to move my lips. I felt as if the train actually went through me. Then finally I was able to move my arms and break free. As I took a few breaths I felt something on my face. As if someone was caressing it with their finger nails. I looked at the clock.
It said 1:50am
It felt like it all happen under a minute.
