The reason I believe in Ghost, is because I am a Psychic/Medium. I communicate with those who have past on and help them get messages across to the living. We get many visitors (ghost) in our home from time to time. And lots of pictures we take have orbs (spirits) in them. My first funeral I went to I was 23, and the deceased was standing behind the casket with another person who seemed (by looking at expressions) to be his guide. The deceased (my unkle) looks at me and says "wow (my Name) is here! then he looked to the right at someone else and I no longer seen him. That was my first experience, after that it was all naturall to me and always will be.
These two photos show my cat (Taylor) first photo he is chillin, second photo he looks up as two orbs are comin at him. Of course we did not see them until photos where downloaded. But the freaking cat saw it.
