It is inconceivable that a person who wrote a book, say 20 years ago, would be able to interpret the meaning of symbols in people's dreams today.

Hahahahah

The books are just the collection of assumptions, just to assume what the dream might mean. The real interpretation belongs to the dreamer.

The reason why lots of people are missing out on the interpretation of their dreams is because they are looking for one man who can give the very accurate interpretation of their dreams, this might not be easily come by, because the interpretation belong to the dreamers.

Even if you end up having someone who is able to interpret your dream accurately, your acceptance or rejection of such interpretation still has a major role to play.
