Where did this phrase come from?
What does it even mean? What does a dream shoot like? I don't think a dream has ever shot anything. Maybe things in your dreams shoot or get shot at, but the dream itself doesn't even really exist. Are they saying they don't even shoot their gun, because that's the only way to really compare it to a dream.
Do they actually mean "shoots like I dreamed it would shoot"? It's a tool, why are you dreaming about it?
Do people lack such creativity or vocabulary that they must use a vague cliche to justify their purchases?
Also, trigger break like a glass rod. I've never personally broken a glass rod, but I'd imagine it would be a very high trigger pull weight if you're comparing it to a glass rod.
