Tired of your vampire getting their rest disturbed by Vaermina's intrusions? Are you looking for a roleplay-friendly solution without completely disabling/reducing the nightmares?
Comfy Pillow for a restful sleep offers such an option by giving some use to a lesser known unique object from the base game: Drarayne Thelas' extra-comfy pillow.
From now on, sleeping as a vampire with the pillow in your inventory will disable the nightmares. Get rid of the pillow to experience them again. Simple as that.
