Does dark nebula has something to do with the dark matter in the universe?

Dark Nebula (http://zebu.uoregon.edu/~js/glossary/dark_nebula.html) are basically galactic clouds that are not "lit" by stars. They are similar to Bok Globules (http://www.ast.cam.ac.uk/AAO/images/captions/aat077.html)

Dark Matter (http://astron.berkeley.edu/~mwhite/darkmatter/dm.html) on the other hand, is a mysterious something that is postulated as existing but has not yet been seen or positively identitified.

The detection of dark nebulae is from the light they block. Think silhouette, shadow. Absorption spectra are the analysis tools.

Dark matter seems to neither radiate nor to block radiation..seems odd. Perhaps it's time to overhaul our paradigms and reorder and resize our epicycles.
