Hallucinations

[keen shore]

Tied to the insanity meter, have things such as monsters and dangerous sounds appear only to the player, while serving no real risk to them. Causes confusion and paranoia when alone, and relies on proper communication when in a group. Should be possible while being entirely client-side.

This adds at least two kinds of visual hallucinations that I am aware of (player that stares at you and items)

Dangerous sounds are prevalent with this mod, although I do not believe it causes you to hallucinate monsters (yet)
