I used to live in a big city and we would drive around at night not doing anything just riding. We seen this old abandoned building looked like a former nightclub. There were chains on the front door and the windows were blacked out and there was red paint with a big x on the back door.
The next night and every night after until we moved, we had a huge bat that would fly into the glass of our bedroom window over and over all through the night. This happened…my husband tried to kill it but never could.
I always thought and still do that the place we seen was a vampire haven and we disturbed them somehow and they sent a watcher bat to try to get us.
