Do you ever believe in ghosts?

[MyDigitalpoint]

Well my answer depends on what you call "ghosts."

Most people refer to the spirit of persons who have passed away to as "Ghosts" but they are really spiritual beings, intangible substance that has not a scientific explanation but animates our body when we are alive.

When we pass away, that energy has to go somewhere, remember the law of conservation of energy; "energy can neither be created nor be destroyed: it can only be transformed from one state to another."

So spiritual beings exist, but in another plane that we can't perceive living in 3D

Ghost are more likely spooks that come from folklore and include demons and other disembodied entities, but matter their existence is truly matter of discussion.
