Figure in the smoke.
I see it. It's a stretch but, sure.
I can see the similarity. The feature most similar to the vomiting scene is the orb. It's probably obvious that Jeffries IS the orb. If the smokey form is suggestive of the mother creature, what would Lynch be trying to tell the viewer?
Interesting, do you think this smoke is in some way similar to the smoke used to show Andy his visions?
