We bought a 50's bungalow a few years ago; the original owner had passed and we were the first people to live there since. My daughter's bedroom was on the far side of the house from mine, and was always colder than the rest of the house. We chalked it up to poor insulation in that room. Every night I would hear her talking to someone; just thought it was baby-sleep babbling. She was about 2 at the time. Then she started talking to someone in the daytime too. I asked her about it, she told me it was the "Blue faced mommy". The "mommy" wanted to play peek-a-boo with her all the time, and wouldn't leave her alone. She said she would wake her up in the night to play peek-a-boo. It freaked the shit out of me. I talked about it with one of the older ladies in the neighbourhood, who knew the original family. Apparently their oldest daughter had suffocated herself in the house after giving birth to a still-born child. (Not sure how she "suffocated herself", the neighbour didn't have a lot of details, it happened in the early 70's.) I am certain that she was the "blue faced Mommy" my daughter was talking about. A friend told me she had read the best way to deal with lingering spirits was to politely ask them to leave. So one night, when my girl was woken up I went to her room and politely said "Please ma'am, your family has moved away, we need you to go now." And after that, nothing. I still get chills thinking about it.
