I think I did believe that Dagobah was Yoda’s homeworld, though couldn’t explain why I thought that. Other than the basics like his house being there, it looking so old and that it seemed to me that Yoda had been there for decades, or he he was so at ease, relaxed and at peace there.
Like screams in the void above, I did think we’d see Luke travel through there as a baby or young child in the Prequels, in reference to his line in Empire.
I’d love to see that art of the serpent creature training Yoda!
