Tears in a dream, if cold, are joy and happiness. If hot, they are worry and sadness. Tears running down the face without crying indicate bad words spoken against the dreamer.

Tears indicate longing for an absent person and loneliness. Flowing from the right eye indicates a matter related to religion, and from the left, a matter related to the world.

Tears are interpreted as joy and relief. If they are of blood, it is remorse and repentance. Whoever sees himself wiping his tears is consoling another in his sadness.
