Readers, please enjoy this guest blog post by Patrick Burke, co-author of the new Ghost Soldiers of Gettysburg. As an expert on battlefield and historical haunting, I am mostly asked questions when doing a lecture or presentation specific to that genre. But once in a while, I get the surprise question that almost always leads me into a new direction of exploring my own Psi abilities and going off the beaten path of paranormal or spiritual world. I was at a conference doing my presentation called, "History with a Twist" and, as is the norm, most of the questions were about the various photos and videos of apparitions or the EVP I captured at various battlefields and historic locations.
