Crying
Psychological (Freud)
Psychologically, crying in a dream works as a release valve: it lets buried grief, guilt or long-pent tension rise to the surface that the waking self denies itself by day. The tears may carry a wish for comfort and tenderness that has remained unconscious.
Oriental reading
In the tradition of Ibn Sirin, quiet weeping without wailing is often a herald of comfort, relief and coming joy. Loud lamentation and wailing, by contrast, are traditionally read as a warning of sorrow or misfortune.
Actions
Dream interpretation is for self-reflection and entertainment — it is not a medical or psychological diagnosis.
