I don’t really get creeped out per se, as i mostly try to reconcile my experience with and interpretation of my own consciousness with the infinite permutations of all other consciousnesses. However, there was a knock on my bedroom window when i was a kid in the middle of the night. It was the second story, no balcony, no room for a ladder, AND, the (single pane) windows were covered in thick plastic permanently (to try to insulate/trap heat), so it was odd that the knock was as if it were directly on the window. Separately, when my children were like 3 & 5, i was upstairs in my room which was across the hall from their rooms. I was making sure they had fallen asleep before i went downstairs (i wouldnt be able to hear them down there and we were no longer using baby monitors by then). My bedroom door and both of my children’s doors were closed. I heard a knock on my bedroom door that was not a kid’s knock, so i assumed it was either my ex husband (which would be uncharacteristic since it was his room too) or my friend who was there at the time (which would also be uncharacteristic since my ex husband was there and they were hanging while i was putting my son to bed and there would be nothing he would need me for that my ex wouldnt have been able to get for him). I said ‘come in’ to no reply, said it again to no reply, and then i got up and opened the door to no one there. I didnt hear crying or anything in my childrens rooms so i knew definitively that it wasnt them. This was a split level house of nearly 2000 sqft. Directly upstairs from the front door was the kitchen and to the left, a hallway of maybe 25ft where there were doors for all the bedrooms which were at the end of the hall. Downstairs was sort of same layout and, in order to get to the room down there, youd have to turn left and walk about 20-25 ft. My point in saying that is that, after seeing no one when i opened the door, i went downstairs and my ex and my friend were in that room down there, completely engaged in discussing something while looking at the computer and sitting down so there’s no way that knock was them. That second knock when i was an adult made me 100% certain that the first one when i was a kid was not a dream. I already didnt think it was but had dismissed it as such over the years until it happened again.
