I have been researching and reading books a lot lately on Lucid Dreaming.

I have been having trouble coming up with academic questions for a 30 page research paper in which it will be based on. The questions are what will drive the paper, and so far I have one since my teacher said I can only really choose the scientific or humanity side of Lucid Dreams.

So my question is roughly; How do we differentiate regular Dreams from Lucid dreams?

Through REM and PGO waves etc.. but I don't know if this will be enough.

I know there are lots of threads that people are writing papers on LDs.. but I really want input on the question and I haven't really found what I am looking for completely.

So i thought I would leave it up to the experts
