ok this is a couple of things thats happend to me,
Youngest one ive had, me and my friend were playing at a building slight, i think we were playing like hide and sleek at the time, but we were mucking around for like a couple of hours. Anyways we were both standing is this room completely silent, then all of a sudden we heard something that sounded like a water drop, except really clean and crisp, we then both looked at each other and said did you hear that then jumped threw that the window and run back home.
This is the more recent one that is the previous unit we were living at.
We lived there for just over a year, first thing that happened was sitting on the couch and something fell down in the kitchen, could have been the wind. Then later one that year i was at work my partner said that she was sitting on the couch again and the fan in front of her turned on. It done this 2 more times at different times.( your guess is as good as mine)
Biggest one. We were both just in bed, the bath room door is closed. You had to lift the door to close is as in the door wasn't quiet lined up. We see this door, it lifts you hear a crunch of the door lift and open fairly slowly opens the whole way but doesn't hit the wall. Like hell i was getting up to check it out. the next day i get up go over to it close the door. I ram into in with my shoulder to see it will open, it doesn't and even when i lift and open it is didn't swing open just stayed where you left it. No explaining that
