Would she rather me die of a heat stroke

Mom yelled at me for running because the dog woke her up. She yelled at me for running IN MY YARD, NEAR THE HOUSE because it's one thirty in the morning. I could've been on the road. It could have been nearly 100 degrees outside. But I was in OUR YARD with it only being, like seventy. There was no danger except mosquitoes. I don't see WHY I was yelled at.
