Ghostbusters ECTO-1

I am a Christian and believe in the Rapture, therefore I do not believe in ghosts. I have a few theorys though. I do not think people who experience these phenomona are crazy.

Theory #1) What if what we think of as ghosts are entirely other beings also created by God? We only use what, like 10% of our brains? What if these beings are here to spur us on to use MORE of our brains to understand and know them?

Theory #2) Emotions give off energy, so I can believe that "ghosts" are residual energy. That is a totally logical explanation.

Finally Theory #3) God sees all time and space at once, could it be possible that sometimes God gives us glimpses of his view? So things that have happened, or will happen, kinda overlap in OUR time?
