"What kind of nightmares?"
The kind that creep in the darkest corners of my mind, the kind where everything is grey and specters  of dreams and fears and hated things come creeping from corners in circular rooms and almost attack me.
The kind where shadowy figures depict who I was and I stab them or shoot them or they burst into flame because I can't let them live.
The kind where I know that everything I care about is dead, or the kind where I realize that I care about nothing and nothing cannot die.
"Have you no good dreams?*
A good dream is one in which there is light all around, where my setting is definite and the demons  attack.
A good dream is one in which I watch as things I love (because in these dreams I can love' dreams don't have to make sense) are whisked away by witches and creatures, in which I see the villains coming for me.
A good dream is one in which I die quickly so it can be over.
I rarely have good dreams.
