apologies if this is in the wrong thread

I've been thinking on this lately - do dreams really destabilize? We all know that starting out, lucid dreams tend to go away pretty fast. What I'm wondering is this: Is it possibly due to all of us here saying such? Is it because of the stories we've both made and read about on beginning lucid dreams that has made us expect the dream to go away on the first go?

This also goes towards doing certain things in dreams, i.e. sex and flying. These two seem to make dreams go away a lot - is this just because we keep expecting them to? The dream world is hugely affected by expectations, so I'm starting to think that maybe, because of all these stories, our dreams keep on going south.
