I believe in them totally. I've seen them. Well i have seen some things that I guess it is just easier to call them ghosts. Never anything like the scarry movies, just strange sightings and feelings of someone/something there. I don't talk about it much as even my friends and family think i'm looney tunse- which I very well may be.
I have, on several occations, been walking in the woods or on a street and had conversations with someone I've passed, and when they say something "profound/strange" I've looked at them and they were not there. I know I'm nuts.
There have been other things too, but there you go.
