A common interpretation of finding something in a dream is that it represents the desire to have that object in your life. If a person sees themselves finding an expensive coat, for example, it may represent their desire to own that coat.
This is not to say that your found object in a dream will be simply a representation of what you need to do in real life, but that the found object may represent something else you are going through or feeling at the moment. For example, if you find a stone or pebble in your dream, this may signify weight or pressure and indicate that you are feeling weighed down by some kind of responsibility or stress.
