The world of spirits is not up or down. It is here, moving at a speed and a different scale. That is the extent to which we all, except the ghosts because they have access to that level until they are released. The level of spirits is concentric with respect to this dimension. There is space in the same area, but did not materialize in our atmosphere.

The esoteric world is all around us. At death, we are immersed in this world. That is the normal transition. However, every so often something goes wrong. A violent death may cause a ghost, for example.

The fact that the etheric be choosing a particular house in response to different reasons. That may have been his place of residence. Another possibility is that in life, has kept a very close relationship with a person living in that house. And also, it can happen, that his death is related to the building and until the mystery is not clarified, this ghost around there.
