An urban legend that began circulating widely in the 1950s. There are many variations, but the basic story is the same. It begins when a teenage boy takes his unsuspecting date out to Lovers' Lane for a make-out session. While there, they hear a report of a murderer who has escaped from a nearby insane asylum; the newscaster says everyone should be on the look out for this crazy man, who has a hook in place of his right hand. The girl becomes frightened--especially when the couple hears a strange scratching sound coming from outside the car--but her date insists everything is fine and tries to continue making out. The girl resists, and eventually the boy relents and drives her home. When they arrive back at the girl's house, the girl exits the car and begins screaming hysterically. When her date exits the car as well, he sees a bloody detached hook embedded in the roof of the car--and realizes that the Hook Man would have scratched through to the interior of the car had they stayed at Lover's Lane any longer.

Nonlethal weapon and ammunition often used by police to control crowds or riots. Spirit hunters also use them as a defense against ghosts and other supernatural spirits. The fired salt alone will not destroy the spirit, but it does act as a deterrent, forcing the spirit to dissipate briefly.

An angel is an ethereal creature who assists and serves God or the gods of many religious traditions. In the Christian bible, angels are portrayed as powerful and dreadful, endowed with wisdom, correct in their judgment, holy, but not infallible. When their duties are not punitive, angels are beneficent to man. When their duties are punitive, they are know as avenging angels and are mentioned in verses such as II Sam. xxiv. 15, in which an angel annihilates thousands on God's command. These avenging angels are used by God to punish men for their sins.

A variation on the Hook Man legend. It concerns two roommates, usually girls. When one comes home late, she finds all the lights are out and assumes her roommate is already asleep. The girl gets ready for bed without turning on the lights. The next morning, when she wakes up, the girl is horrified to discover that her roommate has been viciously slaughtered--and written above her body, in her own blood, are the words "Aren't you glad you didn't turn on the lights?".

Ghosts, spirits, and other supernatural beings often leave behind evidence of their presence. One type of evidence is ozone, which is a poisonous unstable gaseous form of oxygen, formed from diatomic oxygen by electric discharge or exposure to ultraviolet radiation. Ozone can be detected by its smell. The stronger the smell, the stronger the spirit presence. Ability to smell ozone differs from person to person, but most people can smell it at about .015 ppmv. Ozone is also the primary cause in the scent that precedes a rainstorm.
