Wow. Smack down. A bit pragmatic, but poignant.

I agree with most of what you say, but as a matter of self-fulfilment, don't you think that challenging one's ability to control dream elements, even to the extremes, can be a positive exercise in mentation and creativity? And by sharing these experiences with others, couldn't it encourage them to try for themselves, find out what they're capable of, and learn to ask their own questions about the limits of the mind? The only way to push the envelope is to shoot for the stars. Sure, maybe it's still a pursuit of spiritual onanism, but at least it's social!
