A few nights ago, someone knocked on my window in the middle of the night really hard, but I was the only person that heard it. I was too freaked out (as anyone would be at night with mysterious knockings) so I didn't look out of the window, instead I went to the other side of the house and looked out of the door which you can see my window from: no one was there and no noise of anyone walking/running away. I've gone into my kitchen in the middle of the night twice this past week to get a drink and the back inside door is completely open, and I know I was the last person awake and I close all of the doors before I go to bed... Now, I had my tv on mute and there were man-sounding whispers (like talking but I couldn't tell what it was saying, but I could tell it was words). The tv was loading a paranormal show on-demand so I thought maybe it was for the show and I must have already turned the sound back on and forgot. A few seconds later, the show was on and there was no sound. So I clicked the remote and it was in fact still on mute. IS MY HOUSE HAUNTED?!?!? WHY AM I THE ONLY PERSON THAT NOTICES THESE HAPPENINGS?!???!?
