So much stuff man... One experience that I can't even begin to debunk as anything but something paranormal or extraterrestrial stands out in particular.
It was a quiet night and I was cuddled down on bed trying to get to sleep when I start to hear a whirring sound coming from outside. I look towards my shut blinds and see as a bright light makes a pass over my window. I wait a second as the sounds subsides and I peak out my blinds, checking down the street the way the light went. I could only explain the light like if someone walked past, shining a bright flashlight into my window. There was nothing either way on the street so I laid back down. The whirring grew and the light passed again the opposite way and I just kept laying there, petrified. It might not seem particularly weird or scary but this was around 3 in the morning, on the second floor...
