Dreams are fascinating and I do believe that they can "tell" us many things if we only take time to listen.
I believe that events in our dreams (symbols) mean different things to different people. There is no one definition of what a specific symbol in our dreams mean. We must closely examine our own lives and perceptions before we can begin to understand what these symbols mean to us personally.
Keeping a dream journal is essential. Write down as much as you can recall about your dreams and how you felt.
