Islamic Interpretation of Dreams (Ibn-i Sirin):

(Corset; Jerkin; Knee brace; Support) In a dream, a brace signifies tight circumstances, difficulties, adversities, pain, sufferings, weakness and need for someone’s support.

A brace in a dream also may denote resoluteness and determination.

If one sees himself using a brace with a support device in a dream, it means fulfilling one’s purpose, wantonness, containing one’s needs or satisfying them.
