Decapitations and Green Upchuck: a dream in Astoria

Dream: I was working maybe or somewhere with shopping carts. My brother's girlfriend was in the hallway pushing her cart. Maybe I sabotaged her somehow so that her cart went out of control and she and the cart were mangled at the end of a long hallway. I blocked my ears from the noise in anticipation of the crash. Some woman looked at me wondering what I was doing until she heard it too. Cut to me hiking with my brother and him accusing me of being the one who decapitated his girlfriend. It was me, he yelled. She was torn into pieces. I start puking in remorse or sadness or something, but mostly regretting I took my brother's love. The vomit was green as if I had been chewing cud all day, munching on grass. I woke up with a start, tears in my eyes.
