I’ve heard training for lucid dreaming can kinda fuck you up, because it becomes harder for you to distinguish between dream and reality.
I’ve tried it when I was younger (20s). I don’t really remember my dreams now. It is something like a muscle you need to keep using. Write down sentences, draw pics, doodle anything that will help you remember when you wake up.
I didn’t have problems distinguishing from reality, but I did want to sleep a lot more.
You can always stop trying to distinguish between dreams and reality and just accept whatever you’re experiencing as a sort of superposition of both.
The more fantastical elements of lucid dreams are as clearly unreal as playing a videogame. You know you’re dreaming and can control it.
My problem has been more that I can’t remember if something mundane happened in a dream or reality. I’ve had and remembered entire conversations which turned out to be dreams when I referenced them to the person in question.
A lot of my dreams - lucid or not - are just me doing my daily stuff, fully in control of my actions but not the scenario I am in.
