Day 15 of the 31 Days of Nerd Horror kicks off with the novel, In That Endlessness, Our End by Gemma Files. Then we look at A Nightmare on Elm Street, Wes Craven’s nerd horror masterpiece. Next we’ll talk about the cooperative psychological horror game Phasmophobia, and we wrap up Day 15 with a look at the Camarillo State Mental Hospital, said to be the most haunted mental asylum in California.
