Things that happened that aren't 'seeing something out of the corner of your eye':

Watching an earring go down the shower drain, going into my bedroom afterwards and having the earring sitting in some water on the table beside my bed.

When I was but a young dumbass (2001-ish) I did bloody mary at midnight during a thunderstorm. Then I tried to turn the lights on the light bulb exploded. Since then if you try to put a light bulb in it explodes. its been 20+ years, we've had numerous electricians come look at it, but we still have no lights in the downstairs bathroom. Its obnoxious.

I tried to move into a bedroom on the third floor. The girl who killed herself in the room in the 70's disagreed with me and drove me out.

Back when I was in 5th grade, about 2 in the morning, February, some bricks in the chimney fell and crushed the heat exhaust causing the carbon monoxide to back up into the house. My dad had sleep apnea, so he had a c-pap machine, and had 10x the amount of carbon monoxide pumped into him. Carbon Monoxide puts you to sleep then kills you, and it being 2am we were already asleep. He woke up. He woke my mum up telling her he didnt feel good. She said 'something wrong' and got all of us out of the house and called 911, and the fire department came, took a carbon monoxide reading and said 'yeah, you should all be dead right now.'

We've had multiple carbon monoxide detectors in our house since then (1997-ish). The ones with number displays that tell you exactly what the ppm is. (The joke is that carbon monoxide is usually the cause of seeing ghosts, but the ghosts saved me from dying from carbon monoxide - which I find fucking HILLARIOUS)

Some friends and I got a ouija board. we saged the room we were in, and started asking questions. One or two of us would leave periodically to see if the conversation thread would change, to see if someone was doing fuckery - but the conversation stayed steady throughout. I think we ended up talking to 11 ghosts?

Theres probably more. I dont remember all of them, or forcibly blocked them out. I will say, my house was a funeral home for a while, and 3 or 4 people died in my house that I know of, including my dad.
