Welcome Phil

I know where you're coming from, and it's an interesting topic I have seem before. On this forum too
As for evidence, you may want to research the work done by Dr Stephen Laberge, of lucidity.com. He was the most influential modern pioneer on the subject.

As part of his research, he constructed experiments to prove that lucid dreaming happens as it seems (decisions and consciousness occurring during the dream)
Hint: he used the fact that your eyes are free from sleep paralysis in REM
