Although heaven (and hell) are not particularly well biblically supported in the Christian bible, I don't believe it talks anywhere about ghosts haunting houses.
My question is, is belief in ghosts compatible with the Christian faith?
What about other religions?
Christians I have found believe 1 of 2 things.
1. All the faithful will be raised from the dead in the final judgment.
This pretty much does not go with any ghost or spirit belief.
2. You go to heaven (or hell) when you die.
This allows for spirits, however, there is nothing in the bible or anywhere else in the religion that indicates a spirit will "hang around" a house, for example, to haunt it, or otherwise. The spirit will go straight to heaven, or if you are Catholic, you may believe it goes to purgatory.
So who actually believes in ghosts, and if so, how do they jive that with their religion, if they have any?
We Gaels tend to believe that the heavens, hells, and other places religions create are echoes of this world, that, like the Gods and Goddesses themselves, Man has created these places/deities through religion out of subtle energies of the universe, through the concentrated Will of many human beings over time.
We also believe that our Spirits/Souls are also echos as well, created when a person is first born into the universe, a person who doesn't already have the soul of someone being reincarnated.
I also believe that "ghosts" come in a number of categories. The first isn't a separate entity, but a "marked place", marked either by long association with humanity (schools, hospitals, churches, etc) or by calamity, such as a fearsome battle or murder.
Another category involves the atypical "lost soul" someone who is resisting passing through the Veil between worlds for whatever reason.
Another category might be someone from the other side reaching through, whether for mischief or an attempt to reach a certain person that the Spirit might know to give warning, comfort, or guidance.
However, just as standing at the end of a canyon and yelling "Slap!" won't get one slapped, spirits, and Deities, cannot effect human beings directly unless we let them. IOW, they only possess as much power as we give them.
