Is it normal to think about something thoroughly that will never happen?
I have this thing that I do where I think about exactly what I would do if something unlikely will happen. One day I was walking my dog through an alley and I heard the door opening from the back exit to a condo and I automatically thought that there would be someone that would come out of the door, go behind me and cut my neck open, I would run into the the street and someone would call the cops and I would survive but barely. While the cops would come, I would have to describe the killer but I wouldn't be able to. I do it a lot and i wonder if it is something that happens to other people.
