- A being, with an evil that exceeds a person's ability. The devil himself or one of his subjects.
- In mythology and religion: An unclean spirit.
- A being responsible for an daemonic possession.
The different religions each have their own view of demons.
Christianity: Fallen angels, deceased who obey Satan, and "hybrids" who are cross-bred angels and humans.
Islam: Does not directly support the daemon concept. Rather, mischievous creatures, called Djinn, Afarit and Shayatin exist. Their punishment against man must be approved by God.
Hinduism: Does not directly support the daemon concept. As reborn and incarnated, one can be condemned to live life as a restless soul, and may well annoy people. But the incarnated soul is not evil.
Wicca: There are negative energies, but there are no daemons.
In the Western World; demon is mentioned interchangeably, and gradually the word has lost its true meaning. However, in occult and spiritual circles, it is a clearly defined term.
Daemons are shown a lot in TV shows, with quite non-objective and sensational comments. Today, it is unfortunately easy to make pseudo-documentation of daemonic activity using modern aids.
