Of course. But some details turned out to be wrong, but they are minor details, that Laberge concluded, but don't really effect the general benifit and effectiveness of the book's contents.
One of them being that we don't remember LDs if our recall is bad, and may have a LD and not remember it. That is untrue, since we are aware in a LD, and the event is directly stored, and can be recalled later, using that memory, not the dreaming memory(the one that loses dreams quickly, if ever remembered!)
