I use to lucid dream some years back, accidentally, never really intentionally. I have been wanting to try to do it again, but my then I started thinking about and over analyzing it, as I usually do everything. I was wondering if lucid dreaming could do more "harm" than good. Not in the sense that my brain will wither and fall out my ear but I thought that when you sleep, that's your brains time to "rest" [in its utmost brainy resting ways]. When your sleeping doesn't your brain use that time to process what has happened throughout the day and decide what information to keep and not to keep and what not like that? If I intentionally am lucid dreaming does that interrupt something that my brain should really be doing at that time, not allowing it to rest and repose for the next day?

It reminds me of studying for a test. They found people that skip studying hard and cramming the night before and sleep actually do better. So if I constantly am telling my brain to work for me could the opposite happen then it be all fatigued over time?

I guess everything in moderation right? I dunno, any thoughts?
