There is no "ghost's plasma", you're thinking of ectoplasm. They come from the same root word but it's not the same thing. You're right about the ionization bit (molocules that have their electrons shuffled around so they have an electric charge) but not the liquids. There's nothing "mysterious" about them. One sort of plasma is the liquid part of blood. The other sort of plasma comes from milk and is used to make cheese. There's also a type of spotty green rock, bloodstone, which can be called plasma.

If we knew what the Japanese word was we might be able to tell what this "plasma" is.
