Tsunami dream

The Lord gave me this dream last night. The main part of the dream is:

A tsunami was about to hit land. There was a family (a teenage boy and girl, mom, and dad) in a hotel room or condo or something like that. They looked to be of middle eastern descent, with dark hair and dark skin... They were about to run out of the room (they were huddled together in the doorway) when the dad looked behind them out the window. He saw the huge wave and then he heard the voice of the Lord saying something like, "Why should I save you?" And the dad, holding onto his family, answered something like, "So we can tell others about You." Then the Lord told them to go. They were safe from harm and being protected. Just as they left  the doorway, I could see the tsunami wave crashing down. As it was crashing down, I saw a man's body in the water... Then I woke up. It was very intense and real. I knew it was a dream from the Lord, though...

Hebrews 12:25
See that you do not refuse Him who speaks. For if they did not escape who refused Him who spoke on earth, much more shall we not escape if we turn away from Him who speaks from heaven,
