Clouds of plasma would be a possible explanation for dark matter. Dark energy is very different and not really related in any obvious ways.
That aside, clouds of plasma don't really work as an explanation for dark matter either. Plasma interacts with light in ways we understand quite well, which means we would see it in astronomical observations.
Plasma is a "unicorn field"? Explain how its replicated in a lab. Have interstellar clouds been observed in space? Is there a possibility that we are not able to observe all interstellar clouds in space? Has "dark matter" been replicated in a lab?
