This all happened about a week ago I was brushing my teeth, when I heard a knock on the door. Thinking this was my sister, I opened the door with my toothbrush still in my mouth to find that no one was there. Thinking this was just a prank my sister usually plays on me, I turned back in to the bathroom. Just as I shut the door I heard the knock again only this time a little louder.
Once again I opened the door to tell my sister to go away, only again to find no one there. This time I got really annoyed at this so I left the bathroom door open and continued to brush my teeth, when once again I heard the knock but I turned around the door was now shut.
I opened the door to find no one there. I went down the stairs and asked my mum if anyone had been upstairs for the past 10 minutes. She said no everyone but you have been down here.
At this point I got freaked out and decided to just try and forget about it and pack my things ready for school.
I got halfway up the stairs when I heard the bathroom door slam-this slam felt so hard that the door could have probably come off its hinges. I got up the stairs to check, to find the door open.
Feeling brave, I went in and searched the bathroom. Nothing was in there so I turned around to go out when a streak of light past the corner of my eye and then a toilet roll flew at my head.
Completely freaked out by this I ran out of the bathroom and grabbed my school stuff and ran straight for the door. By the time I got there, I was still in shock at what happened.
If anyone can tell me what this was please tell me right away
