Aftermath...

My mothers house in now gone, destroyed in the tornado, and the remains have been cleared, the basement filled in.
Where do ghosts go when the house is gone? Are they still attached to the land? There is one house left in the neighborhood... Will the spirits go there? I am hoping they raise the curfew in town before mom sells her lot. I would like to go take pictures, ask questions, see what answers I can record. I lived with those ghosts so long, it's like losing a member of the family, leaving someone behind.
Is it possible to invite spirits to live somewhere else? If they wanted to move on away from this plane of existence, they would have, right? There is a reason they are still here, and what makes them stay in a place? If they are attached to the land, they are still there. If they are attached to the house - where do they go? Are the forced to move on?
