Mmm, i agree with Tsen - i'm very skeptical about the concept of precognition (and i think you all know what i mean by 'very skeptical'). So as far as interrupting prophecy's concerned, no-one has anything to fear.

But in answer to the more general, post topic, i've noticed a 'bad' correlation that tends to show up in people who love lucid dreaming. It's only a tendency, and only a correlation, and the relationship is with a love or obsession for lucid dreaming, so dreaming itself is not the culprit. But the bad correlation is with depression patients. It's commonly known depression patients are more likely to enjoy forms of escapism, and amongst them, dreaming (and more simply, sleep) is one of them. Depressed people are commonly known to feel 'sleeping/dreaming is the best thing in [their] life', and they express desires to 'escape social consciousness'. That is, the anti-socialness that is related to depression promotes emphasising a person's dreamworld as an escape, a change, from their real world.

So this correlation, this detachment from the enjoyment of real life, is the only thing i could raise as an answer to the question, but i'm not accusing dreaming itself. Most people can enjoy lucid dreaming and be completely undepressed, but a correlation does exist.
