Dream with me as a savior

[saikikudh]

hi there. a few days ago i had a dream again which i could remember clearly.
it was a dream which looked very vivid but i knew it was a dream. it was like this

i was with my family walking at a place. just hanging out.
suddenly i saw a car in the distance coming with a fast pace and it ran into the water. the car was sinking.

without hesitation i ran towards the water and jumped in it. i rescued a man who was driving and his son who was sitting besides him. on the side of the road i was helping them. but i had a feeling inside me that i missed something so i ran back to the water and jumped back in. I swam to the car and saw a woman sitting in the back of the car. unconscious.
i opened the door and i got her to the surface and used cpr on her.
luckily i was on time and she was saved.

-------------

sometime later i was still with my family over at the same place and another car came and did the same thing. and i saved the driver and the kid inside the car. but this time the driver drove in the water on purpose. so i helped the kid and called the police to get the man arrested.

can anyone know what the meaning is of this dream.
I think its time for me to learn cpr. and swimming ;)
