Stalker

Me and my friends were hanging out at our apartment, we were talking with each other and there was something making noise at the window. My friend said "Its probaly a tree or something.". I went to go check and I saw a person, he was running but we don't know where he went because we were on the 7th floor. I told my friends that there was a person. My friends weren't listening and then they left to get some more food. They didn't bring me with them because they were in a rush. I was alone at the apartment, and then. the same thing was at the window. I went to the window very silent but the person didnt run. I went to check and then the monster had my friends. I got really scared and then I called security but they didnt believe me.

So I still live at the same apartment all alone, my friends are gone so I have nothing to do but the same thing happened at the window but I didnt check because I was use to it but I got robbed and then he ran off. I dont know if its a human but, all I know is that, it's not the first time he's done this.
