I've tried that sort of thing, but that's because I'm some sort of masochist. I've been hurt a variety of ways in dreams—though it never hurts as vividly as it would in real life. I've also thrown myself off high places, asked characters to hurt me, and mind-tricked characters into fighting me, so I'm basically a pain-seeker.

At one point I wanted to see if I could become lucid and put my hand into a flame. I wanted to know how much it would hurt, and whether I'd be able to ignore the pain and do it anyway. As it turned out, the pain when I got close was a very intense stinging, far more intense than my usual dream experiences. On top of that, the dream characters nearby had a "Why the hell are you doing that?" reaction, and soon after I lost focus.

Snoop has the best advice for your problems, but I wanted you to know that you aren't the only one to try "dark experiments."
