Ectoplasm

Appearance & Characteristics: Cloudy vaporous mist This term was originally used to describe the substance that  oozed from spirit mediums during a séance. Now it is  associated and referred to as a mist or fog, and it 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. It's usual colors are gray or white but has also  been seen and photographed in several other colors.  Ecto-mist has been caught on both video & all types of  cameras. It's important to note 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. There are several strange characteristics  associated with ectoplasm. It is warm to the touch and has a  wax like composition with weight and mass. It is sometimes a  gelatinous rubbery substance that disappears suddenly  when exposed to bright light. 

Locations spotted: 
All locations but most generally spotted outdoors and most  particularly at cemeteries, battlefields & historical sites. 

Present Theories: 
Believed by many to be the soul or spirit of those that have  passed. Ecto-mist may be the result of a collapsed  electromagnetic cascade shower or perhaps even plasma.
