An injury will suggest a recent hurt, whereas a scar in a dream suggests that there are old hurts, which have not been fully dealt with.

These may be mental and emotional as much as physical, and can remain unnoticed until we are reminded of them. Just as in physical injury there can be many kinds of scars, so there can also be in the other areas. We may, for instance, be left with a pattern of behaviour which is irritating to other people, but without the clear connection given by the dream image, we are unable to understand it.
