Dream of children, kids, mother

I was with my 7 year old nephew and 5 year old cousin. There was a huge beach. My brother and mother were on the other side. We were having a tough time getting to them. I was out of energy and it seemed as if I was sore. We lost our bikes, I left the kids alone to go find them. I talked to a cop and reported the missing bikes. I frantically searched for the children, found them. Then, I found a vehicle. I left the kids and got into the vehicle, driving towards my brother and mother. The car was going so fast, not slowing down, even when pushing the brakes. At one point, I was going so fast off a side I flew, all the way to where my mother and brother were.
