That's fucked up man.

I've had hauntings for sure, but none as frightening as that. The most off-putting one I've actually had personally happened within the last year. My wife and I were in bed at night, and snuggling started to turn into other things. Then somewhere in the middle of things, all of a sudden, from RIGHT next to the bed (like 3 feet away from us), there came a loud, even and very deliberate knocking, emanating from the wooden dresser that's there:
*knock knock knock knock*. We both froze and looked at each other, and I got up and looked out the windows, down at the deck, and all around the perimeter of the house to make sure no one was there, because at first we assumed it was someone knocking on the door or something (even though it definitely distinctly was coming from the dresser). It sounded 100% exactly like someone knocking on it with their knuckle, as I discovered when doing exactly that on the dresser. So after a minute of looking at each other with hesitation, I said "if someone's here, can you knock again?" And within a second or two, the exact same knocking, 4 knocks from someone's knuckles, came from the dresser, 3 feet away from us. So obviously that creeped us out, and was also not cool because we got the distinct impression that it was someone watching us... rather violating, especially for her. I told whatever it was to get some manners and get out of there, and we never heard the knocking again. But the mood was definitely broken.
So the short version of this story is, some spirits are cockblockers. :D
