I finally have my reason for which ghosts exist. But first, I must say that I am Catholic (Yes this does matter).
Since I am Catholic, I believe in purgatory. Of course, no one knows what purgatory is like, so after someone on another site had an argument about ghosts, it got me to thinking. Maybe those ghosts in this world are just people who are stuck in purgatory, waiting for their fates to be decided...
Maybe the reason they are in purgetory is because of something they can try to fix? Then it would make sense if they have to help someone accomplish something.
i find interest in the paranormal, even though i tend to play the skeptic at times...haunted houses & tales of hauntings i tend to collect lots of data on - sometimes, pictures too..
