Sadness dream meaning is explained below using 5 different sources. Each interpretation is shown with its source.

Interpretation 1 — Theresa Cheung

If you feel sad, melancholy, morose or depressed in your dream or wake up with feelings of sadness, your unconscious has used your dream as an outlet through which to release feelings of despair and sadness. Shedding dream tears may be a cathartic experience if you have buried feelings of grief or sadness, and do not wish to put yourself through the pain of dealing with them. If, however, you find yourself repeatedly unhappy or grief-stricken in your dreams, your unconscious may be expressing the onset of depression; such dreams are likely to continue unless you seek professional help.
