The Screams of Brahmin
The Screams of Brahmin is a holodisk in Fallout: New Vegas, and is part of the quest of the same name. It can be found on a nightkin near the McBride house. The nightkin's hatred towards the brahmin is caused by severe psychotic side effects of prolonged Stealth Boy use.
Most of what is recorded here is a mess of incomprehensible psychotic gibberish. It seems to express a general frustration towards a set of brahmin who are allegedly keeping the author awake at night by screaming inside his head whenever he closes his eyes
