When a ghost is in your room

My house some times makes strange noises in the night. One night, when I was in bed, I heard a bang and I thought it was the house but then I swear I felt someone behind me and I was to scared to turn around. Then I felt some one sitting on the end of my bed. I put my head under my pillow. I was starting to really freak out so I counted to three and quickly turned my lamp on, there was no one there. I lay in my bed to freaked out to turn the lamp of. My Mum shouted from her room. "Who's lamp is that?" I replied, "Sorry, It's mine I'll turn it off." So I turned my lamp of and lay in the dark. I'm not scared in the dark but I was for that night only. Then I finally fell asleep. The next night it didn't happen but I was still to freaked out to go to sleep.

This is a true story but I am not sure whether there was a person in my room or not.
