Lost child in the crowded Mall

"I was in a crowded shopping center with my child, and I remember holding his hand as we walked around. Then I looked down for just a second, and his hand was gone. I started calling his name and checking every store. People were walking past me like nothing was wrong. I could hear his voice somewhere, but every time I followed it, I ended up in a different hallway. Then suddenly I was at a playground. My child was sitting on a swing, smiling like everything was normal. I ran toward him, but the playground kept getting farther away no matter how fast I walked. I shouted his name and finally reached him. I grabbed him and held him so tightly that he laughed and asked why I was crying. Then I woke up, still holding my blanket. For a few seconds I was confused and thought I had really lost him."
