Shadow Ghosts

Appearance & Characteristics: Shadow ghosts appear as a shadow of sorts. They look a bit like Ecto-mist but are dark gray to black in color. There are actually three separate types and we list them all in classes below. In photographs, it's easy to confuse them with natural shadows, so be careful with your analysis.

They are usually extremely sneaky and evasive. When they are spotted it's usually out of the corner of your eye or as they are darting through a wall.

They can also be spotted as a reflection in shinny objects and mirrors. As for photography, They are one of the rarest ghost types to be captured on film. Birds and cats are especially sensitive to them.

Type A - Appear as a small dark misty cloud and are almost always under two feet in length, but can hover or float up to 8 feet high.

Type B - Appear as a huge glob of thick cloudy mass. They typically range from 2 to 8 feet in height.

Type C - Appear in human form and some may be seen wearing a hat. They typically appear up to 8 feet in height. 

Locations Spotted: Most often spotted in homes. Have also been seen outdoors at a distance.

Speculations: I guess the general consensus would be that they are ghosts in one of their forms. Some would say that they are demonic spirits or creatures, but that doesn't seem to be the case, at least in most cases.

Origin: first accounts dated back from Antiquity

Description: a bit like ectoplasm but the form is more human-like and less consistent. They usually have a size between one and two feet and travel above the ground. Tricks and pranks have been reported.

Time: any time

Location: seem to enjoy older and larger houses. Very sneaky and evasive, they tend to flee when in contact with humans.

Theory: The spirits of the deceased that remain on Earth, visiting relatives.

Ecto-Mist

Ecto-mist, Vapor, Ghostly Mist;

Origin: 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 it usually displays a swirl effect within a vaporous cloud.

Description: cloudy and vaporous fog (with long swirls) usually of gray or white colors which sometimes takes the form of a human body or a  part of it.  It normally appears several feet off the ground and can linger or travel quickly at will. It's usual colors are gray, white or black but has also been seen and photographed in several other colors.

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.

Time: anytime

Location: generally spotted outdoors and most particularly at cemeteries and historical places.

Theory: supposed to be the spectral body of visiting spirits..
