In which case, why do they not do something useful for a change rather than floating around, disappearing through walls and making loud sounds all night. If they can do that, surely they can clean my car for me, or feed the cat, or perhaps vacuum my office, which really needs it this morning. As it is they are a waste of ethereal space.
Of course we don't know the exact reasons, but my hypothesis is something like this:
Humans are spirit beings who have chosen to incarnate. The reasons we take on physical bodies and live physical lives are numerous. The whole universe is evolving and part of its development includes but is not limited to physical things (the seen universe which can be measured). As part of this ever evolving universe we live multiple lives in physical bodies. When we are not in a physical body it is not part of our primary purpose to be interacting with the physical all the time. Those in the physical have their own stuff to be getting on with and those not in physical bodies also have development and other things going on for them. Sometimes they will visit and interact with those in physical bodies - sometimes they keep away. Their perspective is totally different from ours.
The above applies to conscious spirit beings. Other phenomena which are labelled "ghosts" are simply traces of energy which replay time and again - like footsteps along a corridor for example. That kind of phenomenon is not a conscious entity which chooses to walk a corridor for 200 years - its a trace of something which happened in the past. Since quantum physics teaches us that "time" is illusory anyway, we may even be seeing time distortions. We could glimpse someone walking along who then disappears - are they a ghost or are they a glimpse of the past?
These are theories of course. I base my belief on the numerous experiences I've had with spirit beings.
