I am a cable installer and I work in all sorts of buildings old and new alike. I am also a medium. I have recently been working a building that was built in the 1920's, the foundation was laid in 1918 by a freemason.
Anyway, I was in the basement of the building and there are three walking spaces under the building one is the biggest of the three and has a tunnel in it that leads to an old crematorium.
Well in each of these walking spaces there at least two or three ghosts. In the tunnel space there is a crying woman and a demon as well as a little girl. I have seen all three of these entities and I have been scratched by the demon for protecting some of my co workers.
In the medium size walk space there is an evil spirit it is a male and he does not like me at all. He has choked me and is constantly trying to trip me when I go up the stairs to the ground level and tries pushing me down the stairs when I have to go down to the basement. He has told me that it is because a woman should never work in a man's job. That I am a disgusting disgrace to all women. Now I am completely straight he just hates me for working in a man's job as a cable installer. I do not want to go back to that building I hate it but I need to so I can pay my bills and provide for my son.
There is a little girl who has told me she died from being sick. I think she means tuberculosis. She is always hugging me and she follows me around. She hides behind me whenever I am around my co-workers.
The crying lady has been asking me for help but I do not know how to help her. She seems so sad and there is a little boy who is super shy. I still hate the building regardless.
Either way, I would definitely practice my shielding techniques every minute I was away from that place to insure I was at my best when there. I would also, as ladyglow suggested, keep some sort of talisman or sacred item on your person - even a pocket full of salt - something that you can put faith in.
