I would call it some sort of language, or substitute "sort" with "type" if the word seems too casual for your tastes.
I agree that there may be a lot happening in this world we're unable to perceive, and then your whole argument can be summarized as "anything is possible, we don't really know for sure".
Which I now see is why scientists insist on sticking to things that can be measured, proven and quantified. Anything else is drifting into the territory of religion, superstition and imagination. Humans have been known to worship certain animals as supreme gods after all.

No. Science is a mean to an end, not an end in itself. And intuition, an open mind, imagination help a lot, without drifting into superstition.
Read some history, you'll find out that a lot of scientific (and engineering) discoveries were triggered by imagination servicing some more rational/rigorous practices.

I don't think that's what they mean when they say imagination: imagining things we can not imagine. And science starts with real imagination, then move on to practical, measurable applications.
