I don't know if this topic has already been addressed before, it would be a lot easier to find out if there was a Search engine or something on the site. Just a suggestion.

First off, how come lucid dreaming still sounds very foreign in common society? And though people have lucid dreamt since forever, people still go 'What the deuce?!' when you tell them what a lucid dream is. What's up with that?

Also, when you master lucidity you become completely in control of dreams and can make whatever you want to happen, actually happen, knowing it isn't real, but at the same time feel the sensations of it as if it were real. My question is, has anyone considered that this could turn someone into a psychopath? Since murderers can practise murder and rapists can practise rape in their lucids, and sometimes even ordinary people can get attached to that other dimension where everything is the way they want it to be- sometimes even lose grasp with reality?
Isn't it possible that a master lucid dreamer could get seriously psychologically confused in these cases? Has it ever really happened?

Thanks for taking the time to read all that! Would appreciate some specific answers...
