Dreams about others interacting with our bodies can often symbolize feelings of vulnerability or a sense of invasion of personal space. In your dream, your neighbor cutting your cuticles with a pocket knife may represent a feeling of being exposed or that someone close to you is overstepping boundaries in your life.

Cuticles can also symbolize protection, as they shield the sensitive area of your nails. This action could suggest that you feel someone is undermining your defenses or critiquing aspects of yourself that you consider personal or private. The use of a pocket knife, which can be seen as a tool, might indicate that the neighbor's actions—intentional or not—are perceived as intrusive or harmful.

Consider reflecting on your relationship with this neighbor and whether there are any underlying tensions or issues that could be manifesting in your dream. It might also be helpful to explore your feelings of autonomy and how comfortable you feel in your environment.
