My paranormal experiences

Knocking at my window

I was 11 at the time this happened)I had recently broken my blinds. So anyone who was tall enough could see into my room. I also at that time slept with my light on. So it made it much easier to see into my room. I had gotten comfy, and fell asleep. Nothing strange. I woke up a little later. A bit colder. Still nothing strang. So I went back to sleep. I woke up another time. I heard an incredibly loud bang on my window. Not just one bang but three. I didn't move. I knew if I did who ever was by my window would see me moving. After what felt like half an hour, I looked over at my alarm clock. It read '3:33 AM'

Now mind you nothing is even close enough to my window to do that. I could just be paranoid. Maybe it was a bat? No it couldn't have been. It was too loud and why would it run in to my window three times in a row? If it's a person? You have to be at least 7'0 to knock on my window. Also why knock on a child's window at night?
