what the fuck?

woke up from the most horrific dream I've ever had...
my dear friend was next to my bed, laying on a cot. we were holding hands.
he turned his head to look at me and his eyes were so dark and black.
I tightened my grip on on his hand and he was gone in an instant.
then I hear doors slam.
walking towards the other end of the house- the house I grew up in after my mom married my step dad, its so quiet.
I open the door to what was my moms room, and my child is being raped by a man I do not recognize. her little legs were visible and her stifled cries...
and I shot him in the head.

what the fuck is wrong with me? why would I finally dream of my dear friend for it to be followed by that?
nothing like that ever happened to me. the only trauma in that house was one dog dying naturally in the back yard (a very old stray we took in), and a childhood dog running away to die.

I don't understand. I just do not understand at all.
