The shark has a universal significance as a deadly predator, so if you dreamed of swimming happily at the beach but then were terrified to see a shark’s fin circling around you, your unconscious may be alerting you to someone who is potentially dangerous in your waking world, perhaps even a loan shark who is offering you money at high interest rates. In their positive aspect, sharks reflect power, instinct, intelligence and the ability to survive. In their negative aspect, sharks typically represent hidden fears that may have an intense impact on you. They are also terrifying symbols of death, destruction and the killer instinct. In many cases, the shark represents the fears you may have about what it may mean to strike out on your own. If you are sailing over shark-infested waters in your dream, some things in your life may be compromising your individuality, or you may be experiencing conflicts that are pulling and pushing you in opposite directions.
