@ami and @W. Richardson do you remember our "Ghost Tour" at Gettysburg?? I would have loved to see a ghost - but alas - there was nothing. But at least we heard some good stories!
I listened to it twice and had my husband and daughter listen to it again in the evening. The EVPs don't do a thing for me, but my husband, the physicist, said the blood thing, if it is a time slip is just as disconcerting as a paranormal event!
