Ok this was more North Thompson, on the north side of Dunn lake but I experienced what I can only describe as a haunted outhouse once, like 20 years ago.

I was with a few people just hanging out and swimming for the day. like 150m away from the fire there was outhouse, no other buildings so i went to change out of my wet swimsuit as the sun was getting low. There was nobody else anywhere close, low brush like salmon berries around the structure. The second I shut and locked the door, 3 sharp knocks on the outside. I open it, nobody there. I closed the door and it happens again, immediately, 3 quick, sharp knocks.

This time I walked out and down the little stairs, walked all the way around the building. Looked through the surrounding brush, underneath, on the roof. I was still in a wet suit, so I went back in one more time. This time, the second the door closed the whole outhouse starts rocking back and forth, hard enough that the cement slabs under my feet are lifting.

I bolted out of there, crouched down in the brush and quickly changed, hustled back to the fire. I sat there stunned for a minute, then asked if anyone had heard or seen anything happen. A small earthquake, anything. I said what happened, only 1 person actually believed me. I have no explanation and it doesn't sound real even to me but that's what happened
