To Vault Security: If any of our residents notice any unusual odor or faint taste to the air, please assure them that everything is okay. There was a slight irregularity in our filtration system but nothing to cause alarm; the systems have already been corrected and are 100% functional again. If you notice anyone acting out in a strange manner, please report the disturbance immediately so medical assistance can be sent.
One of the hallucination areas, walking down the hallways from the lower level of the atrium in the living quarters, resembles a server room with terminals that can be accessed to reveal an entry titled "A Note to Me". Several notes with this same name are distributed on multiple terminals in the area, and after reading a couple of them, they will all change to say "Forget it, I'm through talking to you."
Grenades, if thrown in a hallucination, will explode once the hallucination has ended but the explosion won't be heard where the grenade was thrown, but it will be heard elsewhere.
If Fawkes is present for the Tunnel Snake hallucinations, he will see them as well, for some reason, and attack. The same is true for Star Paladin Cross, Charon, Jericho and Butch. Companion kills due to the hallucinations will not cause the player to lose Karma.
The large, unreachable cavern the vault has been built within is visible from windows in the room containing the Science bobblehead.
The male and female bathrooms are on the opposite sides of their respective dorms.
Several additional hallucinations were planned and partially implemented for Vault 106, including a room appearing upside-down for a short time, a hallway where the Lone Wanderer would gradually shrink as they progressed along it, hallways appearing where blank walls had been before, and the "boss" survivor initially appearing identical to the Lone Wanderer's father. Most of these were cut for unknown reasons.
In addition to the unused hallucinations, a special helmet called the makeshift gas mask was placed in two locations within Vault 106. Wearing the mask would have prevented any further hallucinations from happening. The mask was mostly implemented, but suffered from a scripting flaw which permanently re-applied the blue tint whenever it was removed, even outside of Vault 106.

xbox360 If you go into the overseer's office and jump near the wall to the right, near the terminal station, you will fall out of the map. One way to get back is to step into the void, and you will teleport back into the hallway before the office. 表达式错误：未预料的<操作符
The other is to land on the overseer's tunnel as soon as you jump through the wall, face their office and move all the way to the right, and then jump out through small gap in the map to land on a tunnel below (you will lose some health). From there, turn right and ascend the top of the stairs that are the furthest away, forward, from you. After you have reached the top of the stairs, continue heading forward until you reach an opened door, directly east of the door to the vault entrance. If you have not yet encountered this hallucination event, you will be teleported into the hall if you close the door and walk over it.
