Don't be too disturbed by the weird imaginings. If they're particularly weird you could probably write a modestly successful Bizarro genre story. (In my favorites is http://www.amazon.com/Ass-Goblins-Auschwitz-Cameron-Pierce/d... which may be banned in Germany.)
A quote: "We don't have thoughts, we are thoughts. Thoughts are not responsible for the machinery that happens to think them." --John K Clark.
