Overview
Mount Mayhem Haunted House in Phoenix, Arizona
Mount Mayhem: Psykosis 2023
In 2022, our bayou inhabitants wrestled with their demons, and this year, they are now manifesting the resulting psychosis in a myriad of nightmares, real or unreal, trickery of the mind, or simply broken reality. The psyche is clever and what is real or imagined can be impossible to decipher. From hallucinations of whispering voices and visual delusions to the paranoia of being hunted, stalked, and experimented on… the mental torment makes itself known in this season’s Mount Mayhem Haunt, so prepare yourself and don’t let your brain play tricks on you…
