Believe it or not, this is the rare kind of dream symbol that uses your personal understanding of yourself and your capabilities to predict the future. Of course a dream cannot predict what will actually happen in detail unless you are a clairvoyant. But assuming you have a down to earth and realistic understanding of yourself and your own capabilities, whatever future you imagine for yourself should be relatively realistic as well. What seeing a bakery implies is that you will be successful in life and will have a great time with it until you pass on to the next life.
Do you see yourself as being rich? Perhaps you imagine yourself having a large body of work to share with others and you think that your name will be remembered throughout the annals of history. This is quite possible depending on who you are as long as you have a realistic vision of yourself. If you do, then it is very possible that this dream could come true.
The most important part of understanding this kind of dream though is defining success for you. As stated above in a few different ways, there are many options that you can take for defining your level of success. Some people have all of the money in the world and yet they do not feel that they have made any kind of difference in the world, and thus, despair over it. Some people succeed wildly in securing human rights for others and making sure that the rights of humans, nature, and animals are equally respected, and even though they will die penniless, they still consider themselves very successful.
Because a dream is such a personal experience, dreaming of a bakery and telling of your future success only serves to drive the point home more that so much of this has to do with your own perceptions of yourself. If being rich is not how you perceive success then this is not what the dream means, it means you will be successful in another way. All of this goes a bit beyond the main level of interpretation for dreams, but if you can figure out what you think is the defining characteristic of true success, then you should be able to infer a little bit more into what your dream means. You will be able to go beyond just deciding that you will be successful and be able to predict the specifics of your future a little bit better. How about it? How do you define success? Once you have the answer to that question you will know where you will be in the future and will be able to predict many of your own accomplishments. If this sounds like fun to you, then you need to get on that definition and see what you can figure out. Sometimes the hardest part of dream interpretation is interpreting your own mind and feelings about a certain situation.
