"undetectable-through-normal-means matter" is by definition not normal matter. We do not know what it is, so we have a placeholder name for it: "dark matter", i.e. matter that does not shine in the EM spectrum. We have theories about what it is, but most of the mundane ideas (like cold dust) have been ruled out by observations. Now we are left with all these stranger ideas.

Unless you made a mistake in your elimination, which is sometimes more probable than the apparently single remaining truth. Not saying this is the case here, just that this basic principle should be used with great care.
