Recall Knowledge DC 43 (arcana)
Disable DC 48 diplomacy (master) to talk the affected individual out of the killing fugue, DC 45 occultism (legendary) to recognize the spiritual attack taking place and help the victim to resist its effects; four successes are required to disable the nightmare

A vision of a terrifying presence (the King in Yellow, the Crawling Chaos, or some other horror beyond imagining) overwhelms an unfortunate explorer, putting them into waking stupor that quickly turns into a homicidal fugue.
