Indirect Lighting where there isn't any light

So far in my search, I can’t find a direct solution here.

Are these just artifacts that could be solved with increasing my quality settings in Lightmass?
This is the first time I’ve seen this strange lighting using the same settings for other interior lit scenes.

Thank you, anyone, that might have a solution and reason why this kind of bake would occur.
