There was an A.A. Meeting every Thursday night in a very old church not far from my home called Underwood Baptist Church. My dad would attend these meetings every week, so to support his recovery I would come in about an hour early to set up the room for the meetings every Thursday. I would prop the doors open, turn on all the lights, make the coffee, lay out pamphlets and self help books, and arrange the chairs in perfect circles.
I had always had an uneasy feeling being in the church by myself and it was only a matter of time before I experienced something paranormal. It is very old and has lots of historical background so it's bound to have some kind of entities still hanging around. The only thing that looked new was the hideous linoleum they used to cover up the concrete stairs for a more presentable look. In short, the place was creepy as hell.
So there I was, another Thursday night towards the end of autumn. I propped the doors open, turned on all the lights, made the coffee, laid out the pamphlets and self help books, and all I had left to do was arrange the chairs. I had been setting them up for about a minute when I heard footsteps like someone had arrived early for the meeting because this has happened many times before. I looked over and a white haired old lady had come into the room. She wore a white sweater with pink roses on it, glasses, and white pants to match. She started walking towards the coffee that I had just plugged in to be made and I said, "It isn't done yet. I just plugged it in." I turned to fix the chair I had been working on putting into place before, turned back around to see if she heard me, maybe 2 seconds later, but she was gone.
It was a big room and there's no way she could've disappeared that quickly without me hearing it or anything and knowing I was the only one in the entire church was very unsettling. I couldn't get out of there quick enough! It was about another half an hour until someone showed up for the meeting, but while I was sitting there I had been trying to make sense of what I had just experienced, but to this day I can't come up with any reason or explanation.
To my understanding, there was a woman who had recently died in the church so this may explain a little bit of what happened but it still caught me off guard and I still get a little creeped out whenever I think about it again.
I still have the key, but I won't ever go back alone. This was my first sighting of an actual ghost and even though I was scared at the time, I am still very interested in hearing other stories and knowing that other people believe in ghosts as well as me.
