This happened in 1985 I was 24 at the time. I live in Bogota, Colombia. I had a girlfreind who lived with her mother in an old house. They lived far from my own home so many times when it got late I'd stay over.
There are two basically two things that happened to me in that house that really got me wondering in the supernatural. The first was one night I was sleeping in a very small room right down the hall where my girlfreind was slept. and a abouit 1 a.m. the door was pushed open hitting my feet that were close to it, I woke up and heard running towards the end of the hall, I thought it was my girlfriend playing a joke on me so I got up quicky to catch her but instead of seeing anyone I found nothing, I went to her room and found her fast asleep, I woke her and told her what had happened but she didn't belive me.
Afterwards nothing strange happened until some months later when in the city ther was power shortage and evry night from 8 to 10 p.m. there were blackouts. My girlfriends mother had to go out of town for a month and since my girlfriend studied I was volunteered into Babysitting her younger brother (10 years old) and the house to avoid burglurey. I arrived at the house every night a 6 p.m. and at 8 p.m. the lights would go out because of the blackout. every day when I arrived the little brother would stick to me like glue. I would watch TV until the lights went and then with candle light read something. Nothing mucha happened during the first week, then one night in a room next to the livingroom I started to hear footsteps, since the floor was wood you could cleary hear the creaks. I immediatly got a flashlight and went into the room thinkign someone had broken in, but the room was empty, when I got into the middle while I was pointing the flashlight in front of me ther came ! ! a creak from behind me when i turned arounf to see what it was ther came another creak from behind making me turn around again, this happend to me about five times when I decided that wasn't for me so headed out of there closing the door behind me. When I got out the little brother was there scared as hell telling me that he always heard the same noises from that same room. I decided to stay out of there for the rest of the night, bhut i still kept on hearing the creaks. That happened every other night I was there, but I still kept out side.
After the babysitting job I tried not to stay there very much but what I was told by the little brother the noises kept up practically every night.
To keep the story short I never could discover what was going on but not long after a police detective came one day to the house making inquiries about a woman who had died in that hous of child birth, when he showed us a layout of the scene the body was located precisly in the room where I had heard the noises. I don't know if thats the problem or not but to me it could be.
