Sometimes a situation changes,
and what seemed stable now dissolves.
So possibly a concept ranges
from good to bad when it evolves.
Fluid ideas are known to tumble
through our brains when we’re asleep.
In daylight, though, they quickly crumble,
leave only hard facts, far less deep.
How can we judge results that stay
and have effects on what we do?
Brains operate in their own way
which, even hazy, is still true.
