Hi all, Don't worry, I'm not one of those wackos trying to convince you ghosts exist. I don't even believe in spirits. What I do believe is that people are really experiencing real things, but I believe that there is a scientific explanation to it all. I'm not a physics wiz, so I'm hoping to get some knowledge from you guys. Is there any possible scientific cause to explain ghosts? By ghosts I mean apparitions, if you will, that appear in human form, and appear and disappear. Thanks, looking for a good SCIENTIFIC answer.
