The term was originally used to describe the substance that oozed from spirit mediums during a séance from days gone by. It is now associated and referred to as a mist or fog and usually displays a swirl effect within a vaporous cloud. It normally appears several feet off the ground and can linger or travel quickly at will. The usual colours are grey, white or black but has also been seen and photographed in several other colours. “Ecto” has been caught on both video & all types of cameras. It's important to note however, that a camera can inadvertently create this effect artificially in cold weather by a person exhaling to close to the lens when taking the picture. The exhaled breath looks similar to ectoplasm but without the swirls. Oh, and we certainly don't want to be smoking during a ghost hunt for obvious reasons.
All locations but most generally spotted outdoors and most particularly at cemeteries, battlefields & historical sites.
Believed by many to be the soul or spirit of those that have passed on from this life. It has been speculated that the spirit will transform to this vaporous state before appearing as a full-bodied apparition.
