Another explanation is selfishness or the feeling that you don't get what you deserve, you think you deserve more in life. Yet another explanation is that the achievements you have delivered pay off, you will be successful.
A filled cake in your dream or vision tells you that you are on the right track and that you have consciously made choices, full of labor and diligence, yet it does not seem to be completely finished yet. Another explanation is that you feel that you are stuck, standing still or do not have the right options.
When you dream or have a vision of eating cake it tells you that you will be rewarded for your hard work and that you will celebrate success. This dream or vision could also indicate that you want more than you can actually handle, so please be patient.
