I've read Michael Raduga's book cover to cover (Lucid dreams = Quantum mechanics-Yiiiikes!!).
And I've also read the SSILD tutorial.
And I've tried both.

TOTALLY DIFFERENT.

Also, most of Raduga's techniques are Lucid Dreaming's greatest hits rebranded. The Deferred Method is WBTB. The Indirect Techniques is DEILD. Hey, there's nothing wrong with people rethinking and re-tweaking the classics, that's what keeps the collective knowledge rolling along and improving.

I think what makes Raduga original is the way he cycles these techniques together to exponential expand the number of opportunities you have to get lucid every night. And the way he systematically field tested them on people who aren't natural lucid dreamers (Or Phasers-Yiiiikes!!!)

But we're all dreaming on the shoulders of Laberge.
(And he's dreaming on the shoulders of a bunch of really cool Tibetan monks).
