I was a bit skeptical at first but I found this to be interesting. While I don't find myself "travelling to the Other Side" often when I dream, I found her explanations plausible. And I definitely agree with her assessment that dream dictionaries are fine, but a symbol in a dream may mean something entirely different to each individual. I liked her "dividing" dreams into five types, including prophetic dreams, an informational or problem-solving dream, and astral visits.
Sylvia goes into detail to describe each of these "dream types," and points out in our society people don't give enough credit to dreams. She does spend a chapter describing dream symbols, and it's as good a "dream dictionary" as any I've seen.
She also describes ways to make a dream (especially a bad one) end differently by "telling yourself" it's only a dream and to "choose" a different ending to a recurring bad dream.
I felt Sylvia did a very good job in describing dreams and what they mean or may not mean. Several dream books I've skimmed through seem to follow a "template" of sorts in trying to explain what your dreams mean. And Sylvia went out of her way to do the opposite in explaining dreams.
I'm glad I took the time to read this book.
