"Sentient Plasmoid Life" - Could that include ghosts?

You've probably heard of the sentient plasmoid life that Grusch said in his speech. Plasma life? Interesting concept, and it sounds an awful lot of what ghosts are. Plasma is like a shapeless, fluid substance that could take on many difference forms. Kind of like what ghosts do? Interesting thought that maybe there is something to be said about "ghosts" and hauntings and whatnot.
