metaphor
A shark is a relentless predator in the ocean, symbolizing unyielding ambition in the business world. Just as a shark navigates the depths with precision and power, a driven individual pursues their goals with fierce determination. In this way, the shark embodies the idea of survival of the fittest, highlighting the competitive nature of both nature and human endeavors.
Dreams express your own thoughts and feelings; in this case, the dream expresses your anxiety. The shark is a metaphor representing a problem in the family. The dream shows how worried you have been that the problem would "consume" your Grandson.

metaphor
The shark is a metaphor representing some sort of problem. Dreams use exaggerated, overly dramatic images, so the problem "shark" might "attack" suddenly, without warning, but it is not likely to be deadly. This dream could be about the dreamer's concern over the relative. But the relative might also be a symbol, representing the dreamer, who may be the one threatened.
Implied metaphor is when it gives you the metaphor but doesn't tell what the subject is. A regular metaphor tells you the subject of it.
