The fruit knife should imply a series of living environment, distress and worry. People you know cut your right wrist when you are not careful, suggesting that you are worried about being hurt by acquaintances in your life.
If there are no real troubles in life, are you worried about being hurt by your friends? If you don't have that kind of worry, it means that you may have higher requirements for communication security in your life. Or you have a high sense of security and confidence in life, and this dream should be a reverse reflection or reminder of your subconscious.
In short, there should be no problem.
