I'm the same, without having to do anything. Normally, if I don't like where things are going, I jump back in time and do them differently.
But there is another kind of nightmare - those where the things I can find in my mind are.. let's say.. not what I normally perceive myself to be. And I can't say 'It's just a dream', because I'm at least partly concious imagining it, which means it's a part of me.. and you can't wake up from this kind of fact.
This mirrors my typical experience with lucid dreaming, it's more exciting to relax whatever control I have and be entertained (or disturbed). A lot of lucid dreamers report flying, that's so boring compared to the rest! Time control of the situation I'm imagining and experimenting with multiple paths concurrently ranks higher on the fun list than flying for me.
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.
About the banning, I reckon it would be ok, although considered extremely bad taste. I can't imagine a publisher taking the risk. However, it's forbidden to use the swastika at all, in any context (1), so the image on the title page would have to be changed. The book is also not shown in the German Amazon search. (Yes, I'm German.) Sounds very interesting though!
(1)(there have been left groups with emblems with a crossed-out swastika having problems in court for this)
