Hallucination

Regular; Resisted by Will 
The subject’s perceptions are addled. He is completely convinced that one thing that is not present is (or vice versa); he can see it, hear it, feel it, and so on. This is similar to an illusion in some ways, but it exists entirely in the mind of the subject. 
The hallucination must concern the presence or absence of a single  “thing”: one person the subject knows or knew, one crowd of revelers, one pair of shackles on the subject’s wrists, one pride of lions . . . If it can be described as a single entity in English (without amazing gymnastics), then it should pass. The GM’s judgment is final, as usual. 
The hallucination does not require concentration: the subject supplies, unconsciously, all the “realism” necessary. By concentrating, the caster can “direct” the hallucination – put words in the mouth of the absent person, have the revelers head off in a certain direction or start singing a particular song, etc. 
Impossible or obviously false hallucinations (a long-dead uncle, for example) are Resisted at a bonus of up to +5.
