Twice in my life I went on 'ghost hunts' so to speak. One was just out of curiosity and involved a member of a storm chasing team I was on. He turned out not to be a very skilled driver during storm chases, but it was an interesting experience because of his driving. But that is not why I'm submitting this.
At the time this happened, I worked as a trainer for a call center, inbound calls as I won't do outbound calls; they are against my religious beliefs that involving leaving people alone, and a coworker at the desk next to mine did quality assurance for the same ISP. She overheard me talking about a ghost hunt and mentioned her belief that her apartment complex might be haunted. I would prefer she post the experience, but as I have not been able to contact her, I shall share my notes and leave it at that.
She related to me what seemed, to me, to be the usual things that tip people off they may be experiencing a haunting: things moving around, going missing, the feeling of being watched, and feeling a presence with certain strong emotions, usually negative emotions of anger and hatred. I asked her for her address so I could check the newspaper archives for the place, and checked older maps for the city to check out the history.
The apartment complex was near a major university which may or may not be in the Big Ten Conference, and was built in the 1970s. It housed mainly students throughout most of its existence and so had more turnover than some other apartment complexes I know of. Also, being off campus student housing, it seemed there was some experimenting going on: drugs, alcohol, maybe other things too, but there did not seem to be many police runs for drug offenses.
There were, however, many police calls relating to murders and suicides. Either could be the results of personal stress, getting pissed off at folks, or feeling overwhelmed with coursework. This is just speculation on my part as to why there were so many deaths in the rather small complex.
With this out of the way, I tried to do some remote sensing. Something I've done twice before when my dog went missing, I tried to home in on his 'signal', find out where he was and then went to find him with a 100% success rate. When I tried that on the apartment complex, I could not. Something blocked me. It concerned me, but I decided not to push it that way. A few days later when I was in the university area, I decided to drive by. I did not stop for I could feel something decidedly unfriendly. At this point, I decided to tell my coworker I would not be investigating her situation any further and was going to recommend she contact wiser people than me.
(Today, I would refer her to Rook...)
The next time we met at work, she told me she had an EVP to play for me. Now, sadly, I will admit I don't have the recording. I would love to share it and get opinions on it, but there we are. When she played it for me, we both heard her ask: What do you want? A voice responded in a rather hissy sound, somewhat like the sessussulation of leaves in the wind. It said something like ssooollsss. She interpreted this to be solace. To me, it seemed more like souls.
Given what I experienced and learned in the early investigation, I told her, this was a very unfriendly spirit. It may not want her and her family dead specifically, but it would not have been sad if they died. A few months after this, we each took jobs at other companies. We did see each other a few times afterward, but slowly lost contact.
I don't think I can elaborate on it as I'm not that aware of it or experienced enough. Closing my eyes, trying to put my senses in that location and then opening my eyes is about the only way I could describe it.
Hope that helps.
