The sun is very good omen in dreams, because it signifies the choices the dreamer has made. If the dreamer sees the sunrise, then such dream foretells about something new, the fresh start or beginning of the new phase. The sunset is usually interpreted as the end. It could be the end of your sickness or the end of one phase. You are ready to start your new life, because what happened in the past is no longer important.
