Fencing in a dream can signify that the individual is defending themselves against some form of conflict, whether it is with themselves or with someone else. Where the fencing occurs and what the fencing material consists of may be significant. Can also represent being boxed in, feeling restricted or being on edge by your own fence.
Fencing against someone in a dream represents an act of confrontation. In the dream, the individual is fighting with one’s defense mechanisms against a threat that they are not ready to confront yet. This can also represent a person who needs to be more assertive in their life.
