A dream that is not interpreted is like a letter that is not read. - the talmud

Keep a loose-leaf notebook & pen by your bedside.  After you wake, record your dreams in as much details as you can.  Write every little thing you remember, even if it does not make sense or seem important.   Include the feelings you experienced during the dream & those that lingered upon waking.  When you have finished writing, be aware of recurrent themes, patterns, symbolic images & signs.  Do this for one week.  You may want to discuss what you recorded with a dream partner or counselor.  Watch & learn. Did anything previously hidden become clear you?
