impossible dream

Unattainable aspiration pursued

An impossible dream is an aspiration so ambitious or idealistic that it seems unattainable—yet the dreamer pursues it anyway.

The phrase carries romantic or noble connotations, suggesting the goal matters more than the odds: Fighting climate change feels like an impossible dream, but we have to try.

The expression gained currency from the song "The Impossible Dream" in the 1965 musical *Man of La Mancha*.
