The cessation or reversal of a hallucination; recovery from hallucinating.
From 'dis-' (reversing) plus 'hallucination' (from Latin 'alucinari' meaning to wander mentally). This appears to be an extremely rare technical term, if it exists in standard usage.
While 'dishallucination' follows logical word-building rules, psychiatry instead uses 'cessation of hallucinations' or specific drug names—showing that real languages often ignore grammatically valid possibilities in favor of established phrases.
