Entity? Feelings From Another That I Can't Seem To Reach?

I had an odd feeling tonight, I am a security officer and I work the night shift. I don't know if it was because I was alone but I was getting an overwhelming feeling of closeness. Like people or a person were behind me almost attached that's how close it was. It's only at this building I get these feelings, and it's not always just sometimes. I get this feeling like whatever it is wants to speak to me and is getting so angry because it can't or maybe it is and I'm ignoring it by mistake. I was so frightened by this overwhelming uneasy feeling that in my head I just started screaming leave me alone. I don't usually get frightened. I'm pretty strong willed. I had a friend tell me when I was younger she saw a man always with me. A couple years later she was diagnosed with schizophrenia. So I don't know. All I know is that I'm starting to feel like I want to change job locations. Also how does automatic writing work. I remember wanting to do it when I was a child but I've never been able to handle my thoughts. I wasn't really "around" I guess could say kind of like I was in a ship (my body) and myself was inside driving it. I was called absent minded because I never spoke and when I did weird things would come out. Things people wouldn't find funny or very smart. I couldn't help it because I was always sad looking for a place to fit in and recognition. I always wanted to be something else. Like I don't belong, I should be in a different time era. Well I'm rambling now, at 415 am. I hope someone could help me with my problem at work.
