Just a little thing-sometimes at night I hear breathing too. At first i got really freaked and panicked but then we did some research to the history of my house and the last owners had a teenage daughter, Abbey. She died at home from an overdose of ecstasy on her 16th birthday party.
We believe we have her as a semi-benovelant poltergeist...it's sort of freaky and cool at the same time. You know, things go missing and turn up in odd places, yesterday a 50p piece just dropped from the air and hit my dad on the head, but all my mum did was put her hands on her hips and say "Stop it, Abbey!" and it did!
Apparently when i was small my mum heard some noises from my bedroom and came up to see what was happening...I was playing with a toy (she couldn't remember which) and when she asked what i was up to I smiled innocently and said "I'm playing with Abbey mummy."
I scare my friends like that ^_^
