Plus my family thinks I'm into some weird cult now.

Well, first things first, right?
My first contact with lucid dreaming was through my Theory of Knowledge teacher. He mentioned it in class, and after a few weeks came back to the topic and showed us some scenes from "Waking Life"

It's been almost two years since I've graduated from high school, and I had completely forgotten about it until a few months ago, when stumbled upon the Wikipedia entry on Lucid Dreaming.

I'm going to omit the boring details now and just say that last week my copy of "Exploring the World of Lucid Dreaming" (by Stephen LBerge and Howard Rheingold) arrived by mail.
I must admit I bought it on impulse, and I was just wondering if it is as good and practical as it's back cover says
