Lost son in the endless Mall hallway

"I was at a shopping mall with my son, and I remember him asking me to buy him something, but I can't remember what it was. I told him to wait while I looked in my bag for my wallet. When I looked up, he was gone. I started calling his name and checking every shop, but people kept walking past me like nothing was wrong. Then I saw him at the end of a long hallway, wearing a little jacket he hasn't had for years. I ran toward him, but the hallway seemed to stretch farther away. I was getting so upset that I could barely shout. Suddenly, I was standing in my childhood kitchen, and my son was sitting at the table eating cereal as if he'd been there all along. I hugged him really tightly. He looked at me strangely and asked why I was crying. I woke up with that awful feeling still in my chest."
