Dreams involving neighbors and personal grooming can carry various meanings. In your case, dreaming about your neighbor cutting your cuticles with a pocket knife may symbolize feelings of vulnerability or invasion of personal space. Cuticles are protective layers, so this act might represent a concern over boundaries and how others impact your well-being.

The pocket knife could imply that the actions being taken are not only invasive but also done with a sense of casualness or lack of care. It might reflect anxieties about trust and the intentions of those around you, particularly someone you interact with regularly.

Consider reflecting on your current relationship with this neighbor. Are there any underlying tensions or issues that need addressing? Alternatively, this dream could be prompting you to examine how much control you have over your own life and personal boundaries.

If you feel comfortable, think about discussing any feelings of discomfort or concern with your neighbor, or take time to reinforce your boundaries in other areas of your life.
