Crazy Voices?

Does anyone else ever suffer from crazy voices in your head?  Not like a serial killer wanting to kill, Kill, KILL, but those voices that sneak into your head when the house is quiet, you've gotten into bed and are ready for sleep.  Doubts and insecurities rush in spinning around madly, gleefully dancing, bouncing around in your brain like ping pong balls.  Sleep is no longer possible.  Rational thought joins the fray trying with all their might to fight off the negatives with their strength, shooting back reality at the mad dancers.  You toss and turn, searching for peace, praying for your brain to quiet, wishing for a surcease, grasping for the sleep that is ever out of reach.  The war raging in your brain seems to have no end, on and on rational thought battles against the demons of doubt and insecurity, trying to restore the equilibrium the brain yearns to find, needs, in order to sleep.  Exhaustion marches onto the field. more tired and crankier than usual, to put it's foot down, ending the war.  Each are commanded back to their own corners, doubt and insecurity assuring rational thought that they will be back to battle another night, but for now, peace reigns, the brain relaxes and sleep finally comes.
