Source: The Great Interpretation of Dreams (Ibn Sirin)
(By analogy with a wound) A bandage in a dream indicates concealing a matter and hiding it. Applying it indicates trying to fix a corrupt matter.
Source: Perfuming Humanity in the Expression of Dreams (Al-Nabulsi)
A bandage indicates the removal of worry and healing. Removing it indicates the uncovering of the matter.

A bandage is interpreted as goodness. Whoever sees himself applying one will attain goodness.
