What does this dream mean?

[Mizuki Chan]

sounds like a freudian theory dream because like you said "rsing singer who you like."
dreams are from our subconscious and they tend to reveal themselves in our dreams. The freudian theory sates that they're "sypholes into our unconscious, fears, desires, and emotions that we're usually unaware of. They make themselves known through dreams; wish-fulfillment."
I don't know which singer you're talking about but srsly, someone can't be famous just because they sing good. Others sing pretty well yet they still don't have contracts and all those fancy schmancy.
Ok so back to the dream. If this guy's not famous yet, I'm guessing you want him to be famous; like you said "He will soon be famous due to his singing"
