To dream of a bare razor blade represents conflict in your life that requires you to be absolutely perfect. Feeling that perfect adherence is required. Facing a problem where there is no room for mistakes.
To dream of a razor blade with a handle represents your wish to restore a problem to absolute perfection. Taking your time to put something back in order. A store bought kit such as Gillette may reflect a better idea to restore a problem than someone else has.
Example: A man dreamed of wanting to buy a Gillette shaving kit. In waking life he felt that his idea to flat out sell his deceased Grandmother’s house was a better way to totally finish off his family’s fighting over the will. Other family members wanted to wait and were discussing business proposals with the property that everyone wasn’t in agreement with.
