Is Lucid Dreaming in any way bad for teeth or liver??

Yeah I know it sounds insane,but I came across a comment recently on the imdb discussion forum for the move "The Good Night"
Does anyone has any idea of this??

Never heard of that before or this movie... interesting. A lot of those commenting on there have no idea what they are talking about. You can do anything you want in dreams. That includes light switches and looking at your hands. :) anything is anything.

I do wish there was a movie about LDing and went over having trouble stabilizing and doing LOTS of things people do in LDs. I would also love it if it had parts that it got blurry and he had to stabilize or say things like "clarity!" that would be fun to watch.

I found no relevant results when googling "lucid dream liver" so I don't think that is a true statement. Plus this guy said some other things that don't make much sense, like "Without a journal he would not learn lucid dreaming even in ten years" I'm sure you can find lots of members on this site who never used a dream journal but still experience lucid dreams, or "First thing everyone does is flying. Otherwise you will not be sure if you are having a dream or if you are awake" which I know is wrong from personal experience, I have had a couple lucid dreams before I ever tried flying.

If it's bad for your liver, then sleeping is bad for your liver.

Living is bad for your liver.

The liver is bad for living.

"Yes, you can learn to control when you wake up and even you can go to sleep in your dream and have a dream within a dream which looks even more real."

:facepalm:
