Do you have an example? I can’t possibly think of a single idea that’s completely expressionless. Even drug-fueled hallucinations can eventually be given a description; albeit without being able to actually transfer the feeling/internalization of it.
You might have to be overly verbose and explicit in your language, but ultimately you can describe pretty much anything using “like”, “as”, and “akin to” with qualifiers.
I think that any parent holding their baby for the first time will give an example. There is a feeling of existing, of purpose, of continuity. But no "like", "as", or "akin to" suffices.
