I don't think it gets in the way of dreams and lucid dreaming...it just means that with working nights your REM phases will be different to the rest of us, and that's what you need to work out.
I work shifts, a mixture of early and late starts. I find that if i go to bed and i'm on an early start the next day, i don't have any dreams, because i'm woken up at 5am and my REM phase is between five and seven am.
If i'm on lates, or days off, i don't have a problem!
Hopefully this clarifies your situation. Feel free to PM me if you need any more assistance.
