Crabs, claws, and the empty Kitchen

"I was walking along a beach when I noticed a few crabs crawling around my feet. I tried to step around them, but there seemed to be more every time I looked down. Their shells were different colors, and some of them were surprisingly big. Then one crab grabbed the bottom of my pants with its claw. I tried to pull away, but it wouldn't let go. I remember laughing for a second because it looked almost ridiculous, and then suddenly I was scared. The beach disappeared, and I was standing in my kitchen. Crabs were crawling out from under the refrigerator, the cabinets, even the sink. I climbed onto a chair and just watched them moving across the floor. One particularly large crab stopped right in front of me. It raised one claw like it wanted something. Then my phone rang. I reached for it, and when I looked back, the kitchen was completely empty. I woke up wondering why I had been so afraid of those strange little creatures."
