I think real. If there is suppost a soul in a person, that can either go to heaven, hell, limbo, or be reincarnated, then there could be such things as spirits.

I have personally seen spirits or ghosts. I probably will write my experiences on here as soon as I have the time.

Ectoplasma, Ecto-mist, vapor, ghostly mist.

• Cloudy vaporous mist.

Orbs, spears, globules, balls of light, globes.

• Mostly photographed abnormalities.

Vortex, funnel ghosts.

• Usually a swirling funnel shape.

Shadow ghosts, dark entities.

• Shadows of some sort.

Apparitions, disembodied spirits.

• Transparent human form and wear clothing of their period.

Ghost lights.

• Usually seen as white or blue balls or yellow spheres floating in the darkness.

There are more types, and most of them I have encountered before. All of these I have encountered.

There is more information on ghosts or spirits on Ghost Study. This is where I got most of my information on this page.
