I know what you mean! Sometimes we wish our dreams would become reality. Sadly that's not the same for me. Whenever I dream about vomit, it's always someone else doing it and I get anxious even in my dream, and I wake up sweating with a racing heart. And it's always about someone that's very close to me and there's nothing I can do to help or escape. I guess it really boils down to confronting my fears.
