I wonder if stories like this are of someone passing through to the "other side", why are some places haunted...are those people ones that cannot pass through? Is it always because of something bad happening in their life?
Hauntings most often are caused by energy which hasn't dissipated, perhaps it has been "imprinted" in a place. This might result in seeing clouds or hearing noises. You might even see a person - a "ghost" - but that person just repeats the same actions without noticing anyone around it. It is thought that such appartitions are not actually conscious beings, rather they're just energy of a being who used to be there which is somehow replaying.
Entities which can interact with us, such as TallTexan's little girl are usually not stuck in a place (IMHO and in my previous experience which admittedly is limited). They choose to be at a place to relay a message or to simply visit it as part of their acceptance of their own passing. They might occasionally come to see those they love, for instance.
Some entities hang around a place by choice because they know that there might be a chance for them to make contact or somesuch. Unfortunately these are fairly often what they call "lower" entities. A friend of mine's husband encountered such an entity in a hotel loungeroom. He and a friend both saw a dark cloud which loosely resembled a person which hovered and went through a wall. He had never (and has never since) seen anything like that before and was a skeptic until that point. Only afterwards did they discover that only days before a psychic had held a seance at the hotel and many residents were encountering the entity.
Just my thoughts...
