One time i was at home with my mom, my sister and my two roommates we were just in the living room chilling and talking about life when we hear the doorknob to the bathroom start to rattle like if someone was stuck in the bathroom but then it had stopped so then we continued talking then we had heard it another time but. then it stopped again. Then on the last time it continued to shake but this time someone was pounding on the door like aggressively and the door was rattling aggressively too so i went to go open the door and when i had opened it there was nobody inside. We had all got scared and we all ended up going to our rooms and going to sleep.
