Dark meat, receding Water, and the averted Mother

"I was eating meat at a table with some people I don't really know. I think it was beef, but it looked different, almost too dark, and I kept wondering why nobody else seemed to notice. The plate was already in front of me when I sat down. I don't remember ordering it. I took a bite and it tasted normal at first, then suddenly it was very salty. I wanted some water, but the glass kept moving farther away whenever I reached for it. Someone across the table was talking to me, but I couldn't understand anything they were saying. Then somehow I was eating the same meat in my childhood kitchen. My mother was there, but she wasn't looking at me. I remember feeling uncomfortable and trying to stop eating, but I kept taking another bite. I woke up with the strange feeling that I had forgotten something important."
