I would like to share my experience with a Ouija board from around 8 years ago.
A group my friends and I constructed a rudimentary Ouija board out of paper and a glass. We dimmed the lights and made sure that everyone in the house was in the same room, along with the dog. This house is an old Victorian era house in England of which I don't know the history.
Upon starting the session we asked basic questions, "Is there anyone here?" etc... And had a little success. However, as we continued we started to notice strange things happening in the room. Firstly the dog was freaking out, barking at random spots in the room and staring at nothing. This was the first unsettling thing.
The temperature in the room dropped considerably and there was a feeling of someone watching us and breathing on my neck in particular. Then various things happened all at the same time, The curtains blew out into the room, although the window was completely shut; the candle stick on the table lit up without a candle in it, stayed on for around five seconds and went out again, and loud knocking was heard on the table and walls.
This is when everyone freaked out and finished the session. One of my friends threw the glass at the wall, which just bounced. I then tried to break it, thinking it was a fluke but it bounced again. This was the last straw for everyone and we bolted out of the house.
Even today everyone is scared to talk about this when we chat about the past, and everyone has said they have felt and seen other presences since this day.
