Last time, we discussed imaginary friends that turn out to be not so imaginary. Yesterday at WraithStop™ while discussing an article titled "Cold Spots: Fort Delaware" I mentioned the "schism in ghost lore where there are photos of half seen figures not seen by the eye, but at the same time accounts of ghostly figures indistinguishable from the living until they disappear or do the impossible like passing into a wall." What I did not mention, because this is the more appropriate venue, is that there is a rules framework that brings together both of these elements and many others that don't necessarily seem to fit together. This does beg the question if it can just be that there are disparate haunting phenomena going on that do not interrelate. The answer is of course, yes, if you want it to be that way.
First let's look at the theories that make for a cohesive set of rules for ghostly manifestations. It starts with the idea that much of it comes down to energy, and some of it to the will of the spirits in question. It starts with a ghost hanging around unseen, watching things happen. At this base state it may or may not show up in a photograph, depending on how much energy it has. When it has enough energy it becomes visible to the naked eye with the translucency depending on how much energy. Other acts such as telekinesis require energy and may or may not impact on visibility. A ghost with enough energy can chose to remain unseen or reveal itself to someone even if it has no control over its current photogenic quality. Overarching, this all may be dependent upon whether it is an active, intelligent, spectre or a residual haunting played on a loop, or not dependent on that criteria at all.
It is certainly an option to have different kinds of ghosts and hauntings that each work off of their own rule sets with as much distance or overlap as desired. Poltergeists can be noisy mischievous spirits or they can be purely psychic effects of the living. Unintelligent hauntings can be echoes of the past or entities caught up in the energy of previous events. Intelligent ghosts can be earthbound spirits or conversely non-human spirits such as devils and non-corporeal species beyond our current understanding. There are other events that can be described as a haunting such as Shadow figures and people, doppelgangers, humans travelling astrally, black eyed kids and people, and watchers and thought forms, which are ghosts created by human belief. As with everything else your setting can incorporate whatever manners and meanings work for you.
