Dream within a dream

Date: 5/2/2017

I took a nap today as I was very hungry, I started dreaming that I was at my job Bj's and I was at my register. A couple came through my line and they had all this food on the belt, and in my dream I fell asleep at my register and began dreaming about eating all their food. I woke up from my dream at the register and they said "jeeze we were wondering what you were doing." I woke up and said yeah sorry I had a dream that I ate your food. Then I actually woke up in real life.
