-In [[SLASH'EM]], hallucination also distorts items the hero is standing on as well as their 1inventory, which makes it a far more hazardous ailment; additionally, you cannot name specific objects or object types until the effect wears off. Avoid quaffing a suspected potion of hallucination without a remedy on hand such as a unicorn horn, set to an inventory letter that you can remember.

 In addition to the usual sources, eating a [[mushroom]] or a pink [[pill]] may also cause hallucination, and applying a [[medical kit]] can cure it. However, a hero's [[deity]] will still consider it a minor problem for purposes of prayer.

 ==Description==
-While hallucinating, [[object]] glyphs will be seen as continually changing items of the same class - a [[pick-axe]] may be seen as a [[sack]] or [[dagger]], but not as a [[monster]]. This also applies to items in your inventory or on your square, but the actual appearance of those items will be accurately reported when looked at. Monsters themselves will cycle through various appearances, and whether or not they are hostile is obscured; monsters cannot be named while hallucinating. This perception changes every time the screen is updated, so even selecting an object or monster and pressing {{kbd|;}} to see what it is appearing as will change it to something else. Hallucination abuses [[wisdom]] every 5 turns for its duration.
+While hallucinating, the [[hero]]'s perception of their environment will change every time the screen is updated, even when simply [[far look]]ing or starting and then aborting an action: [[object]] glyphs will be seen as continually changing items of the same class (e.g., a [[pick-axe]] may be seen as a [[sack]] or [[dagger]], but not as a [[monster]]), although the actual appearance of their inventory or items on their [[square]] those items will be accurately reported when [[picking up]] or viewing those items. Monsters will also seem to cycle through various appearances and cannot be [[named]], and whether or not they are hostile is obscured. Hallucination [[abuse]]s the hero's [[wisdom]] every 5 turns for its duration.
-The set of names chosen for monsters while hallucinating includes a selection of various names from popular culture and entertainment, e.g. Barney the Dinosaur, King Kong, the Luggage, the Mother-in-Law, and The Ravenous Bugblatter Beast of Traal [[Hallucinatory monster|among others]]. The same applies for any mention of [[Hallucinatory currency|gold or zorkmids]]; similarly, hallucination replaces various standard messages with [[Hallucinatory messages|more humorous ones]].
