Why are there haunted graveyards?

Although it might seem pretty obvious as to why graveyards are notoriously haunted, bodies are buried there, right? This is really not enough of a reason, if we view this explanation logically. After we are dead, it is reported by those who have had a near death experience that the first thing we do is look back with complete disinterest on our own physical bodies. This makes sense, since the life force has left the body and there is no longer any use for it. It does seem clear that some spirits do have some sentimental feelings, or a compulsion to return to where their human remains were put to rest. More of this thought after the jump.

From author Susan Sheppard: 

Some theorize that spirits hang out at cemeteries drawing upon the energies of their decaying bodies, claiming energies in the cells still fire, but I doubt this, since many ghost anomalies appear in very old historical graveyards that have not had a burial over many years. Instead, it appears that cemeteries may simply be an opening or a portal for the spirits to pour through, almost like an airport or bus station for ghosts.

Perhaps the reason is cemeteries are places where events of high emotion take place, such as funerals. Graveyards are also a place where we reflect upon the lives of people we have lost, or at least, we are aware of another’s loss. Perhaps this provides just enough inspiration or contemplation to pull the spirits down. Not matter what reason behind cemetery haunting really is, there is a plethora of evidence that points out that this phenomenon exists. Therefore, if you are looking to gather evidence of haunting, a public cemetery is a good place to start out. Try not to trespass after dark, if there are signs that say they prohibit visitors after dusk. Dusk is a very good time to take ghost pictures. Sometimes you can notify the ground-keeper and get permission to go in after dark.
