Writing a research paper on lucid dreaming

Hi guys, I’m currently working on a big research paper on lucid dreaming. I’m trying to cover two major topics: lucid dreaming’s physiological detectability and therapeutic benefits and I am completely stumped. What I’m trying to do is establish that lucid dreaming can be identified as a detectable phenomenon (mostly using LaBerge’s eye signal research) and that lucid dreaming can be beneficial in relation to psychotherapy. What I need are good resources to prove these points or any help in general, as I’m starting to realize that my current sources are not enough to prove my point.
Can anybody help me find good resources?

Regarding LaBerge’s research, you could probably find the paper if you know which journal(s) he published it in. I think that his findings provide an empirical basis for the detectibility of the state of awareness within a dream
