Wow! I've just spent the past week reading the whole thread. The experiences you guys have had are amazing.
I must say that I'm very glad that I appear to have no sensitivity whatsoever. The house we own (we're currently renting it out while we live in another city for my husband's job) was the site of the previous owner's suicide. We didn't find that out until after we had put an offer on the house (in my home state, suicides are not required to be disclosed to potential owners, but murders are). We decided to go ahead with the house purchase and haven't had any unusual experiences (fingers crossed!)
The city we live in now, and even the building we live in, has been home to many horrific things over the past hundred years. There is a building just down the block that witnessed many, many terrible events during the time of Nazi occupation. Many visitors have said that they feel an overwhelming depression when getting close to the building and have questioned why we would live so close to it, but I haven't felt a thing. Thank goodness, because I have an overactive imagination, and it wouldn't take much to scare me away.
The only stories that I have that have hints of paranormal activity are from when I was a child - and I had that previously mentioned overactive imagination, so I can't be certain of the stories' veracity
The first is that I had a small clown doll that was handmade by a friend of my mother's and given to me when I was young (I think as a baby). I had no particular fear of clowns and I actually loved the circus, but I started trying to throw the doll away suddenly when I was about 6 or 7. My mom asked me why and I told her that it kept appearing on the foot of my bed when I awoke in the mornings, when it had been sitting on the dresser when I went to bed that evening. She said it must have been my sister moving it as a prank (which is absolutely something she would do) but she denied it, both then and to this day (we're in our thirties now).
In the same house, we had an intercom system in all of the rooms. At night, I would hear a male voice coming from the speaker in my room, but it wasn't my dad's voice and he was sound asleep when I went to my parents' room in terror! My parents had no idea what to think of this but said it was probably interference from some other electronics. This was in the 80s, though, so there wasn't an abundance of cell phone signals around
In that same house, I often had recurring dreams about a ghost in the hallway that looked like my sister, but when I tried to speak to it, I would see my sister standing in another room of the house. I haven't had any dreams like that since we moved from the house when I was 10, though. So again - was it the product of an overactive imagination? I think so... since I've never experienced anything since that time... but I guess I'll never know for sure.
