Complete Dictionary of Dreams
by Dr. Mıchael Lennox
A razor blade is a very small but very sharp-edged metal tool.
The combination of its size and ability to cut very deeply is symbolic of the way in which innocuous moments can hurt without warning, like a sharp tone of voice or sudden action that hurts someone’s feelings deeply.
If a razor blade appears in a dream, either you may be experiencing such wounds from someone in your life or you may be the one at risk of hurting others without meaning to.
