Steven K lay on the couch in Dr. Ash Granger's office, recounting a dream. "It's like every night this past week. I'm at the grocery store and I'm shopping. Stock boys are putting goods on the shelves, other people are shopping. They smile as we pass each other. Their carts are full of food and household goods and I see some of them lined up to check out but I'm pushing an empty cart. Up and down the aisles. I'm checking items on the shelves, but I don't buy anything. But here's the weird part," he said.
