Dreams within Dreams

I dreamed I sliced a loaf of bread using the edge of my hand.
I dreamed I was in a parade.
I dreamed I bought a shack at Carpenter's beach and it was painted blue inside and was set up like a concession stand with a soda counter. Where would I sleep? I was having buyer's remorse.
I dreamed I was with my dog Lily. I ran into a friend selling hot dogs and I was telling her about my beach shack dream.
