I tried to tell my friend that lucid dreaming is not dangerous...

his argument is that:
1. It is not natural thus it is unhealthy as you are not supposed to be awake while dreaming. You are not supposed to control your dreams

Some random clips of his convo:

Friend 11:58 pm
and even with reality checks there are concequences with things you do
and messing with your brain is not a good one

Friend 11:58 pm
you should let it do what it has to do
and not mess with it
when you start messing with it
Friend 11:58 pm
you can screw it up
Friend 11:58 pm
when you lucid dream you are artificially making yourself do it and when you do you are imagining which is fine but like you said it will be so real there will be times that you will lose reality
Friend 11:56 pm
your creating it
or making it
making it artificial
and that is whats not good for your brain


Here is what I told him:
1. It is natural, you train yourself to reality check, so when you go to sleep you un-consciously do a reality check and realize you dreaming. Then your logic part of the brain turns on and your in
2. You are not controlling you "brain" you are just aware that you are dreaming and with enough practice can change the dream around as you please (and here he says its un-natural).
3. Scientists never found anything dangerous about this.
4. Some people lucid dream without even knowing how to do it or what it is, aka naturally.

I will show him this topic tomorrow when he wakes up (so post reply's as if you are replying to him) and hopefully you guys can explain it better then me.

I'm not the best at explaining things anyway.

Just tell him why it is not dangerous and why lucid dreaming will not harm you... Because i cant seem to put it in proper detail.
