I saw a ghost.

Ecto-whiz. Cool!

I belive you dude. Many people think time is linear, but alot of theorists believe it is like an onion, with many layers. People fail to realize matter is meerly energy reduced to a slow vibration and in close proximity creating density and mass while still only composing the same electrons, protons and neutrons. Traditional Penta-sensorists(people who believe "real" consists of what can be seen, felt, smelled,tasted or heard) have lost or refuse to acknowledge the 6th sense or 3rd eye. Premonition, ghosts, 2nd sight et al are the results of the remnants of the human ability to tune in to the electromagnetic fields( similar to how birds and many other animals navigate and communicate) and energy remnants from previous alignments of matter.

Or maybe it's easier to call BS.......BEER ME!
