A wall, fence, or other divider or barrier could have many different meanings, so consider its context and how you feel about it. Some possibilities are:
- An obstacle or challenge
- Something that keeps two people apart, such as a disagreement or being in different locations
- Protection, separation, or an attempt to distance from another person or situation (as in "putting walls up")
- An attempt to keep things out, or keep things in, contained, or controlled
- A wall in a house can represent separation between the different parts of your life (for example, a house with no interior walls could mean you feel you have no boundaries between your work life, home life, and family life, etc.)
