Like people have hinted at, dreams have often been part of fortune telling. Generally speaking there is no way to know what if anything a dream might indicate without Divine help. Even in psychology we really have no idea how dreams work. People like Freud and other people in the psycho-analysis have speculated on dreams, but I have yet to see any scientific verification for any of their ideas. Dreams do seem to have a connection to body and mind as we see, for people’s health or life circumstances seem to affect dreams. As a previous post mentioned some theorize that dreams are involved in consolidating memory, in this care particularly in the hippocampus, but even this, as far as I am aware, has not been scientifically validated and remains speculative.
