The Tight Shackle
Scholars have said that seeing a tight shackle might indicate a constriction of affairs for the dreamer in the place where they are shackled. For a joyful person, shackles might signify the continuation and increase of their joy. If a shackled person sees themselves with an additional shackle, it might indicate death if they are ill, or an extended imprisonment if they are already incarcerated.
