One-handed dream meaning is explained below using 1 different source. Each interpretation is shown with its source.
Interpretation 1 — Martha Clarke
To dream that one of your upper extremities is amputated is a sign of the inability to complete one of the activities you normally do with that arm. Behind it all is a fear that you must try to overcome. Don’t forget, equally, arms symbolize your ability to relate with others. To see yourself without arms, therefore, denotes a serious emotional problem.
