for the second one, I think that the person could be experiencing happiness, opening their eyes, and seeing the real world through a positive lens. They're seeing the world, trying new things, etc. For the third, I see a very warm and cozy yet still strange household, different from the rest of society. The strange plants flourish there, and so do the people inside. It's also very bright inside the house compared to outside, so the house could be where they feel safe. dunno what's happening in the first one.
