Elemental Ghost 

1. Non-demonic, unexplainable apparition or entity that exists at the edge of human sensory frequency.

2. Spirit, being, apparition or entity which inhabits nature; can effect environment by means found within nature. Sometimes attributed to being a fairy or protector of nature.

1. An apparition or entity that cannot be fully perceived is called an elemental or elemental ghost. Something that moves too fast for the human sensory range is perceived as a blur and cannot be seen clearly due to its rate exceeding the frequency where it will properly be perceived.

We saw an elemental ghost last week, it appeared as an unexplainable black haze moving quickly effecting the environment around it.

2. There's elemental ghosts found all over the German black forest!
