Ghosts are real. The following is condensed from my second book, Voyage Beyond Doubt
"Several times a year I get calls from someone concerned about a ghostly presence they're aware of, usually in their home. Some callers are frantic, worried the ghost might do them harm. Others are more concerned for the welfare of a ghost. There are some simple things anyone can do to permanently move a ghost out of their house. Before getting to them, let's cover some basics and hopefully clear up a few misconceptions.
First, the most important thing to know is that ghosts are just human beings not living in physical bodies. These are people just like you and me. Like people everywhere, ghosts can be friendly, scary, smart, stupid and everything in between, but they're just people.
Second, at its most basic, the reason you can be aware of a ghost is because its attention is focused at the level of physical world reality. There can be many reasons why ghosts do this. They may be unaware they're dead and staying close to familiar surroundings or people. They may be aware of their death, but confused about what they're supposed to do. Some ghosts may have a message they want to give someone still living in the physical world. There are lots of reasons why a ghost's attention may be focused at the level of physical world reality, but that focus of attention is what brings them to your awareness and keeps them here.
Third, you have nothing to fear from a ghost. Despite what Hollywood horror films would have us believe, such a person is not a threat to you. Projecting your own fear onto a ghost can certainly appear to give evidence to the contrary. Too many people I work with bought into Hollywood's fear-inducing images, and are scared out of their wits, thus adding to their problem.
Fourth, there are Helpers living in the nonphysical world who will gladly assist you in your attempt to move a ghost along. All you have to do is ask. Often the Helper is someone actively trying to assist the ghost, but unable to reach him. Sometimes there's a Helper waiting to move a specific ghost. The Afterlife abounds with Helpers willing to volunteer their assistance wherever such an opportunity presents itself."
So again, yes, ghosts are real. They're just human beings stuck in Focus 23 close enough to physical world reality that some of us are able to perceive them.
Editor's Note: Bruce's books contain accounts of encounters with ghosts and his removal of them from people's homes, as well as tips for amateur ghost busters.
