Most often, a plate will symbolize what you are serving yourself in life. Compare your dream to what is going on in your real life. Is “your plate full?” Do you have too much going on? Do you need to make room for more me time or more family time? Or is your plate empty or broken? Do you need to fill your metaphoric plate with more emotionally fulfilling activities?
Plates and dishes can also refer to the current state of your health and your diet. Look at what is on the plate in your dream. Do you need more of that food in your diet or do you need to eliminate it?
