Strange dream...?

This dream seems to relate to you taking control of your life. You are holding all the parts but there is an internal struggle reflecting some uncertainties you have. It would seem you are afraid to let go and go for your ideals because if you do you will release a monster (the shark) and it might devour you. You can either stay where you are and hold tightly onto the tank or you can let go and seek what you want even though there are always dangers out there.
