Ghosts and Spirits Were Once Human

I watch all of the ghost hunting programs on television and am also part of a group that does investigations. I belong to the "Inspired Ghost Trackers" group and we investigate historic properties, hotels, private residences, etc. when asked.
  One thing I notice is that a lot of people seem to forget that ghosts and spirits were once human. They were people like you and me. They may have had a partner, or children, or a dog or cat. They worked for a living. They struggled through life and had celebrations. They went to school. Then, their physical body died, but their energy stayed behind on earth. They became an Earth-bound ghost because they chose to, for forgiveness, unfinished business, or some other reason.
  People choose to stay behind as Earth-bound ghosts or move into the light with the other spirit energies. Those who stay behind find themselves trapped here.
  In fact, if you ask a ghost hunter the most common thing they pick up on EVPs, you'll hear "Help me." Ghosts are trapped here and need help getting into the light.
  So, next time you're on a ghost investigation, tell the ghost to "go into the light." The light to the spirit world can be found in hospitals, funeral homes or cemeteries. Or, if you're knowledgeable, picture the light and try and open a portal yourself. Help ghosts cross over and find peace. That's ultimately what they're looking for -
just imagine yourself being in an isolation cell away from your families (who are spirits that have crossed). You want to be with them, just as earth bound ghosts want to cross into the light and need to join their deceased relatives. So, "Help them!"
