I once woke up in the middle of the night to what sounded like an intruder tripping and falling in my bedroom bathroom. I ran to the kitchen and got a knife, I saw my doors were still locked. I ran back and tried to open the bathroom door slowly and immediately there was some pushback...like somebody was trying really hard to keep it closed. I tried again and I could barely open it an inch before it was pushing towards me more...as if the intruder was leaning against the other side of the door. Fortunately, it was just the shower curtain that had fell and become jammed in between the door and the shower...I was still freaked out trying to figure out how to get in the bathroom because I didn't know why it happened.
