Why do people see ghosts? Do we see them simply because they are there? Or are they there for a reason,to perhaps tell us something? Several times over the last few months I have seen people I know are dead, or think I saw them. One I knew personally and 2 that I knew in passing or had worked with. The 1 I knew I saw across the parade ground but close enough that I recognized him. the other 2 I have seen more than once in various places. I sleep well, I don't have bad dreams that I recall. We are given a psych evaluation each time we deploy or return and I pass. So why all of a sudden do I see dead people.
