—Yesterday Was Frustrated
Insanity is a status condition in Fallout: Dust. Insanity is caused by indiscriminate killing, cannibalism, use of hard drugs, addiction and general trauma. Insanity can be treated by using the drug Thorazine.

Hallucinations
A character suffering from insanity is prone to intense hallucinations, some of which induce a fugue state (see below)
Ghost Town
As the player approaches the cart near the saloon, they will be attacked by bipedal plague victim. Upon attacking or being attacked by the player, they will explode causing a fugue.
A player entering Victor's shack will encounter a Securitron with a distorted face speaking in static gibberish. The Securitron will explode when shot.
A player entering the general store will be attacked by a child plague victim with the body of a skeleton. This too will explode when shot/attacked.
Freeside
Shadowy apparitions (blacked-out Sierra Madre holograms) appear on various rooftops throughout the south end of Freeside. Shooting them causes them to explode.
Entering the cloud-filled alley near Mick and Ralph's causes an oversized super mutant to charge the player, exploding on impact.
Upon passing the entrance to the King's school of impersonation, a massive centaur will emerge from the alley immediately in front of the Strip gate. This too will explode when attacked.
The Prison
Upon killing the occupants, child NPCs will begin to appear in the yard and visitor center. It is unknown if this is caused by insanity or a glitch. Though it is more likely to be a glitch as in Alchestbreach's playthrough of Dust the event occurred when he wasn't insane.
Jacobstown
The road leading to Jacobstown is occupied by Shadowclaws (Blacked out deathclaws) who will attack on sight. Attacking or being attacked by these creatures will cause a fugue state.
The Sewers
The blacked out hologram ghosts will appear at various points throughout the sewers.
A dead child NPC can be found with the name "Your sanity"
Shadowclaws can be found in the cages near the monument.
Fugue States
Upon entering a fugue state, the player will be transported to a multi-floor upside down version of the starting safehouse. The bodies of the survivors who initially attacked the player will be replaced with those of two child NPCs named "Hope" and "Peace" respectively. Both carry the note "Nursery rhymes for the unsound of mind" which reads:
(Name) is a murderer
(Name) is a thief
(Name) eats flesh and pretends it's beef
Throughout the fugue safehouse, there are several doors encompassing the upper two floors which will take the player to various places throughout the Mojave. Most of these will take the player to various survivor shacks at throughout the map while at least one will take the player to a slot canyon inside Hoover canyon. A final horizontal door on the top floor will take the player to the lowest floor of the New Vegas sewers. Upon using this door, it can be seen on the Pipboy map marked as "Nightmare" but cannot be accessed through conventional means.
