I have been lucid dreaming on and off for the last year or so (averaging once or twice a week when I practice actively), and yet I am still having trouble with dream control. Recently I have been doing a lot of reading about expectation and its influence on the outcome of dreams as well as the amount of control we have while lucid, and I have had a disturbing thought that I'd like some feedback on.

I am a scientist by trade, recently out of college and moving into a grad position. I have been trained over the last 5+ years to think logically and base hypotheses about the world on evidence. I am wondering if this has hindered my ability to truly expect some of the impossible I should be able to do in dreams. Even if I am fully aware of the fact that I am lucid and that should give me all the power I want, my senses tell me things should be ordered in a reasonable way; that I should not be able to teleport, fly, etc. because that isn't scientifically possible. Many times I have practiced telling myself while lucid, "This is a dream, I can do anything I want," but I always feel deep down that I am never able to fully convince myself. I am not a religious person and struggle with faith-based outlooks, which certainly seems to be what the expectation game in lucid dreams is all about.

Has anyone else struggled with rationality/reasoning/scientific thinking getting in the way of dream control? Any suggestions to help remedy this?
