I know it's not Halloween, but having perused property, I thought I'd ask the question whether you've lived in places you believe were haunted. I've had two.
The first was feeling someone breathe on the back of my neck. I had my hair in a ponytail, and was hanging up my coat. I heard it and felt it but pretended I didn't notice as I was freaked out. It was a long exhale. Then there was the time in the same place where I thought I heard my then BF come in downstairs (we were in a flat) and hid behind the living room door, giggling and waiting to jump out after I heard the door slam. After a few minutes there was nothing so I came out and no-one was there.
I bought a terraced house, built in 1773. At the top of the stairs one day, I saw the shadowy figure I'd seen out of the corner of my eye for months come running up the stairs. Frozen in fear, I turned and felt this thing pass straight through me, turn left into the (now) bathroom and saw it leap through the window. That shit me up. 😳
I also stayed in a hotel once over Xmas, in Whitehaven. I came downstairs for dinner and was having a chat with the owners and told them of a weird 'dream' I'd had of a man standing over the bed, wearing a short cape with a Jacobean wide brimmed hat and that I'd looked down, but couldn't see his legs below the shins. The owner went white, rushed away and came back with a book describing the very same, which she'd bought after the house purchase. She also told me that the ceiling under the room I was in had been raised. Freaky moment.
