Sorry, rant ahead:

I mean, I don't get the whole thing.

I realize I'm dreaming almost 100% of the time when I'm dreaming, so I'm not a lucid dreaming denier, because I do it all the time. That being said, I don't have strong 'control' over my dreams like some people claim to have. I can't be like 'okay, I wan't some lightning, and a purple frog over here, and a big red carpet to fly on'. I honestly doubt that many people, if any, can do that, but they sure as hell claim to.

So even if there is someone out there with 100% control of their dreams, how could you ever verify that? Very suspicious sounding to me. Until we can even verify that someone exists with that level of control over their dreams, and that your average Joe can also do that (with some practice) I'm extremely skeptical.

And even still, so now you can use your dreams for super powers, like becoming a better painter. Just dream you're a master artist (because you can dream anything, remember) and that will help you in real life too. Such. Bullshit. It honestly mirrors many self-help ideas. One that comes to mind is a guy-I don't recall who exactly- who became a 'master' (he honestly was mediocre-amateur level at best) painter and wrote some shitty novels because he simply 'imagined' himself doing these things effectively. I think his tactic was to imagine himself as his best novelist self or something. Really focus on the imagery of him being a novelist and penning a novel, and the words are all so good, etc. And boom, he writes a (he thinks is great) novel. Classic self-help bullshit.

Why not spend some quality waking time picking up a paintbrush and practicing painting like a normal person rather than spending all of this effort on some dubious pseudo science?
