First off, i have never experienced someone like this in my lifetime. I do though experience some shadows and light figured out of the corner of my eye at times.

Well this story is a little different. I was in my room past midnight by myself with the lights off, but a lamp illuminating my desk. I was on my computer video chatting with my from from school and we were just talking and sharing snowboarding links through the chat. Out of nowhere i heard deep heavy breathing. I couldn't figure out if it was coming from my computer or somewhere in my room. I stop talking to my friend for a couple minutes and just starred at one spot on my desk. My friend was puzzled why i was doing that. I asked my friend if he heard a deep breathing but he looked at me like i was trying to scare him. He said it was not him and that it couldn't have come from his room through the video chat. I was somewhat freaked out since this was abnormal, so i just tried thinking about something else, and eventually went to bed and fell asleep.

Just wanted to share my experience with you and feel free to leave comments.
