Etwold

Does anyone know where I can find Exploring the World of Lucid Dreaming online line like an ebook or in PDF?

That would be illegal... Unless by on-line you mean you are going to buy it from www.amazon.com

I don't quite understand the question but i bought it on ebay.

I do not believe ETWOLD has ever been released in electronic format. As mentioned, the only copies you would find like that would be pirated.

Please support the guy who took Lucid Dreaming into the realm of scientifically proved reality. The book isn't very expensive at all, and can be had from any bookstore.
