I grew up in a haunted house, so many of the things I took for normal until we moved when I was a teenager and realised just how creepy it was.
examples: always seeing someone out of the corner of my eye when looking in mirrors, a man with black hair, my Mum always said I was imagining things but others saw him too and after we moved she admitted seeing him also.
Footsteps thumping up the stairs but stopping just before the top.
Putting something down, turning around and it being gone, moved somewhere else with no one around.
Taps coming on full blast then turning off just before you reached them and being turned so hard that it took my Dad to get them back on again.
Ornaments randomly jumping off shelves.
The feeling of someone sitting on my bed in the night but no one there.
Hearing light switches snapping on and off in the night.
The dog barking at nothing, loud bangs from rooms with no one in them, I could go on and on.
These things weren’t constant, it wasn’t like a horror film but they added up and when we moved I couldn’t believe how different and ‘lighter’ the new house felt, I’ve never felt anything like it since either in any house DH and I have owned.
