Theory#5 Ghost Exist Only As Figments Of Our Imaginations.
May I perhaps submit a Theory#6 which combines all others. (Yes, I love to be difficult!)
Which goes something like this...
Ghosts are Earthbound Souls (Theory #1 ) in the case of active haunting or Events recorded in our surroundings (Theory #2) in the case of Residual. These energies reside in an alternate dimension any only cross over into ours occassionally (Theory #4), and when they do it can leave traces or be triggered by electromagnetic conditions (Theory #3). And in many cases what we see or experience are not so much PHYSICAL experiences but rather past experiences, sights or visions we have seen which are drawn upon by these spirits to interact with us. (Theory #5).
Did I cover everything? Hope I didn't leave some out.
But in honesty that's mostly where I'm leaning in my personal beliefs.
