I am new here, this thread caught my eye. To me sleep dreams can have meaning or not. Some can be random processing.... (IMO) Many do have real meaning.

I have considered dreaming while awake, in a theta state (lucid dreaming as called), as in before you fall asleep and are aware of the dream, as more a "vision" having merit and meaning. I never considered them to possibly have the random, or no real meaning a sleep dream can sometimes be (IMO), I have viewed them as special and to be looked at seriously. I believe visionary dreaming is a sign of awakening and awareness myself. (excluding mental conditions that can cause them also). To me this is a fascinating topic.
