kory At the end of Mother 2, the characters spirits return to their bodies with a little animation. Very common to depict spirits physically this way. Did you finish The Return? There’s a very fun spirit-bowling-ball scenario ahead, no spoilers.
On the subject of the Woodsmen though, some of the characters in Twin Peaks are named directly after their role in the story, Bobby Briggs being thrown into jail, for example. The woodsmen, symbolizing telephone poles or trees or something, log lady etc. The characters in Tazmily Village are all named stuff like Lighter, Fuel, Flint, etc. to reflect their part in the story.
The way Lumber is used as weaponry by Flint and Lighter, later Lukas to a lesser degree, is also an interesting choice.
