Seizure?

Something weird happened today. I got up and stretched. After stretching I felt dizzy so I laid down. I woke up on the other side of my room in a corner, but it felt like I was sleeping. I was shaking like I was having a seizure and I seen tall black legs in front of me. I looked up, and it appeared the person had no face. no way! that can't be real, I said. He looked down at me, then I blacked out. I woke up again, in the same position. I felt hurt, like I was tossed around. Then, I just got up and continued with the day. Like nothing happened......
