Terrifying gifts, really.  

They come to you at night, invading your bed and flooding you with dark images heavier and more brutal than you could possibly comprehend in your waking world.  They hold you captive--you are vulnerable.  Naked and twisted in your sheets, tethered to the dreamworld by their presence. 

They watch and wait for you to drift off to sleep, all the while collecting ephemera from your thoughts and fears and daily interactions. These they will use to weave together the Gothic landscape they plunge you into.  Yet as much as you fear the coming darkness, the tortuous hours spent at the mercy of these demons, there is another part of you that pines for it, that calls them to you, that eagerly awaits their presence in your bed.

As terrifying as your nightmares are, you have still come to see them as dark gifts of insight upon waking, cleansing your soul and bringing the much-needed release of psychic revelation.
