Welcome to the forums spec.

Wow I think its the first time we had a newbie post right off a topic on how not to have lucid dreams.

The only practical suggestion I can give you is to forget totally forget about control. If you can chance a few bad dreams that is. I agree with Alric, nothing in nightmares can hurt you, just remember that.

Another possiblity is to get the BWGEN program and use one of the presets that allows you to sleep without dreaming and see if that works.
