Re dream interpretation:

Dreams are an idiolect -- a dialect of one person. The symbology in it has meaning to them based on their life experiences and much of it cannot be meaningfully guessed if you don't know the story behind the symbology.

This means it can be useful to keep a dream journal, say, in therapy to try to figure out what you really think about your life when no one else is around. It's generally much, much less useful to hear what other people think of what you dreamed. (There are exceptions.)

Re astrology/tarot/fortune telling:

The stock in trade of most fortune tellers is asking good leading questions and thereby getting the client to tip them off as to what kind of feedback you are hoping for. Whatever advice they give you is only as "wise" as the person giving it and in most cases has little to do with what the cards/stars/tea leaves/whatever supposedly say.
