I woke up in the middle of the night and found a stranger in my bed

I (23F) live alone in a ground floor flat in a building where everyone has an allocated carparking space with multiple visitor spaces. I have an allocated parking space that is right next to our verandah which has a small flight of stairs leading to my front door. <br><br>It was a Saturday night and I had a friend come over to watch a movie. When he left at 12.30am, I locked the door and went back to bed. I forgot to lock my screen door and it wasn't until the next morning that I even realised. <br><br>At around 2.30am I woke up because I felt a really tall guy sitting in my bed and his head was right next to mine on my pillow. I freaked out and jumped up and started screaming as much as I could. As I jumped up, I physically touched this guy's face and he let out a really loud yell but he jumped off the bed and ran out the door and I heard the fly screen bang shut as he ran for his life. <br><br>I was really shaken up and now I'm always checking locks and looking over my shoulder and I'm finding it hard to sleep alone.
