Ghosts in Another Room?

I enjoy watching the ghost hunting shows on television with my partner, who is also a certified ghost investigator on the Inspired Ghost Trackers team. One question he asked was "why are ghosts always in the next room?"
  Think about it. If you're watching "Ghost Hunters" or "Ghost Adventures" or some other ghost hunting program, usually investigators hear noises in another room.  Why do you think that is?

  I believe it has to do with the personality of the ghost. Remember that ghosts maintain the personalities they had when they were living, breathing people. Some ghosts causing activity in another room may be shy and not want to directly confront the living, yet, they want to let them know that they exist. It's like shy people who want so much  to let people know they're in a room, but are afraid to come up to someone and talk to them. So, the shy ghosts make noise in another room as a "cry for help." Usually, a ghost's cry for help means a request to help them cross into the light to join their loved ones.
  Another personality trait th may be the reason a ghost makes a noise in another room instead of in the direct presence of someone, is that the entity may enjoying playing/toying with people, and trying to scare them. People who were controlling or power hungry in life, would be controlling in death. Those kinds of people who are now earth-bound ghosts, would enjoy scaring people from a room away, making them wonder what happened in another room.
  Whatever the reason for a ghost making a noise from another room- it's all to get attention to let the living know they're dwelling in a place, and they want help crossing into the light.
