Abstract

Nightmares are intensely negative dreams that awaken the dreamer. Frequentnightmares are thought to reflect an executive deficit in regulating arousal. Withina diathesis-stress framework, this arousal is specific to negative contexts, thougha differential susceptibility framework predicts elevated a...
