A Hallucination is defined as perception of visual, auditory, tactile, olfactory, or gustatory experiences without an external stimulus and with a compelling sense.
They are also a form of altered perception. Hallucinations can be caused by powerful torture of the soul, War (the Horseman) and ghost sickness.
Some ghosts can create supernatural illnesses, for example the Buruburu can create a form of ghost sickness that makes the subject hysterical, hallucinate, easily frightened and eventually die.
During a majorly of Season 7, Sam, with "the Wall" broken in his head, was having intense hallucinations of Lucifer, which had gotten to the point where he could neither sleep nor tell the difference between the reality and his hallucinations.
Cuthbert Sinclair also produced a Werther Box that triggered hallucinations upon anyone who failed to undo the security mechanism.
In Season 12, Lady Toni Bevell used hallucinations caused by an unknown potion and spell, to extract information from Sam Winchester.
Hallucinations[]
Here, situations and occurrences of hallucinations are briefly documented.
- Lucifer - He used this ability on Nick to convince Nick to say "yes" to possession. He did the same again to Vince Vincente.
- Horsemen - War induced a small town, making the inhabitants see demons, until his ring was removed. Ellen, Jo, Dean, and the townspeople were confirmed to have been affected by it, though presumably everyone was affected.
- Djinn - Monsters which are able to infect humans by touch which cause the victim to experience incredibly realistic hallucinations, capable of convincing them that they are in a perfect world or confronting their worst fears.
- Wraiths - These monsters can cause effective hallucinations with a simple touch. They have used this ability against Dean Winchester, Sam Winchester, and Martin Creaser.
- Hellhounds - When close to their prey, hellhounds cause their victims to experience hallucinations, so as to frighten them out of hiding and leave them defenseless.
- Buruburu - Luther Garland infected the people responsible for his death with ghost sickness, including Dean Winchester, forcing the latter to see hallucinations of Azazel and Lilith.
- Werther Box - Causes whoever fails to bypass its security defense to hallucinate. These hallucinations will drive those afflicted to commit suicide.
- Lady Toni Bevell - As a member of the British Men of Letters, she also taught and knew many spells. Toni was able to use a potion and powerful spell to cast realistic hallucinations to Sam that are even able to push him nearly to his limit. With the help of Chinese technique, she created a very potent hallucination of Mary Winchester being mentally strangled.
