Do ghosts exist??

I know of a ton of people who believe in ghosts because they know people who have claimed to have come in contact with ghosts or claim to have personally. If ghosts really did exist, then when a loved one dies wouldn't they contact you? There are so many people who say, 'Oh, I've seen ghosts.' Or, 'I heard footsteps when I was alone for the night.' When you are extremley upset over losing a loved one, if they turned into a ghost you would think instead of watching you suffer over there loss, they would somehow show you they were there, & allow you to continue on with your life. What are your thoughts??

I don't kno what a ghost is. I'm skeptical though. I think a lot is just people making money from stuff- or their belief in mysticism is quite far fetched! I don't think spirit's still keep a corporeal form. I think once you leave this earth-hoever that is-your body, senses, etc. leave also.

I'm sure though that everything we do leaves behind an energy trace of some sort which could be replayed later. But I'm not really concerned about being scared of this stuff. What I find fascinating is that its still exact to spacetime events. What I mean by this is that if x event occurred at y place and time then if the earth is moving, then at time and place x+1, y+1, given that it is highly unlikely that the event occured at a time and place earlier in the universe exactly the same as experienced at x+1 and y+1 there is some mystery there. Unless, of course, perhaps, when we travel into a space and time even that has been occupied before, we get a sort of replay of what had happened earlier. Food for thought.
