If you dreamed about writing a letter to someone: You may feel the need to share your feelings or be supported emotionally, a day where you may encounter people who tend to make small things bigger. Writing a letter to someone in a dream indicates that you live by enjoying life, wishing for the good, a happy peaceful life and life gaining meaning. Receiving a letter from someone and not replying in a dream indicates that you are not in good mental health and you live a depressed life.
