I think I found a retard-proof kind of "explanation" that is superficial enough for you (btw crack pine was funny because, as far as i know, you do drugs and i don't - so what an amazing reference).
"But what if ghosts are something else? Could it be possible that what we see or experience as a ghost represents a break in the continuum of time? In other words, if we view time as not a linear construct, but rather a wave, or even a loop, could we be looking backwards (or perhaps even forwards) in time when we observe a ghost, or similar phenomena?"
