There is too much activity going on in your life. Your dream is a signal for lost innocence. A person disappointed you or this person suddenly fell ill.
Dirty fish tank dream represents your inability to confront some subconscious issues or feelings. Your goals may be too high and are impossible to realize. Some issue or some aspect of your life still remains unresolved. This dream means what is holding your relationship together. Your view or understanding of some situation is wrong.

You are at a critical turning point in your career, and now someone is throwing you yet another curve ball. Your response is to collect more information. Instead, you need to cultivate wisdom in order to process the information you already have.
