Electric, horses

Gathered in a large home with expansive grounds. The home apparently belongs to my family. There is minimal lighting inside. I wander around, and in my little brother's room find a switch and turn it on. A bulb appears dangling from the ceiling (kind of track lighting ?) and it gives off a fluorescent blue light. One of my older brothers appears and we decide it will be a night light, for the light illuminates the long hall outside of the room. Meanwhile, our younger brother is outside with a crew of friends and folk. There is a race set to begin: horses and cars and bikes. I am a little nervous that my daredevil brother will get himself hurt showing off. The house is surrounded by a large circular gravel drive. There are parks on the grounds too. I walk outside trying to catch a glimpse of my brother among the racers; I cannot tell who is who. The race begins and I make my way across the estate to the other side by benches, and where the drive expands into the width of a real street. Horses are charging down, cars are zooming, and I am worried all the while. I keep scanning the racers when I finally catch sight of my brother: he is jogging! A sense of relief and surprise overcomes me.
I am then running down a lush green path with a male friend. He is on his phone with his girlfriend assuring her that we are on a work assignment. We are running and running when I suddenly see ahead a large tree splitting through the roof of a big house. I stop my friend just before he steps on an electrical wire, and remind him of what happened to my brother's landscaping friends (true story). We peer down and can see children playing inside the home. We decide to go down and see what has happened. We carefully make our way inside of the home, and find the children and a mother. She doesn't seem at all surprised that we have climbed inside her house. She shows us around briefly, but mentions nothing of the tree. She seems to want us to stay. I begin to feel uneasy, and my friend has disappeared and so have my shoes. I tell her I must go and begin to climb out of her home when she tells me that I can walk out of the door. She is sitting before a television, and has a movie paused, I don't want to keep her from watching it so I make my way quickly to the door. The house is really an apartment I realize once outside the door in the building hall. I find my way outside and find a huge unpaved lot. It is industrial looking there except for the house. I begin to run across the rocky lot, barely touching it fearful of glass and wary of the deep puddles.
I make my way to the street and up ahead see a shopping plaza. I notice there is a Kmart there and think of how I can buy a pair of flip flops - should I ask a stranger outside to do so for me, or risk breaking the "no shirt, no shoes" service rule. I remember this Kmart from another dream; I have been here before. I grow a little relieved knowing that I only need to walk a few miles on the road ahead to make it home.
