Here's a sleep-med-fueled theory. What if Mado is a Japanese-Peruvian who grew up in Peru, returned to Japan (maybe as a teen with her parents, giving her no choice), couldn't handle the culture shock, and became a shut-in? She still dreams of Peru, which is all she knew grewing up, even though she failed to fit in there despite wearing a native hairstyle. Her parents would have told her stories of Japan, and maybe of the internment camps in Peru during WWII, and it all would have gotten jumbled in her unconscious. Now a young adult with agoraphobia who can't adjust to living in a highly urbanized country with over 10 times the population density of where she grew up, she feels very hemmed in and trapped, and also culturally unmoored - thanks to her parents' genes she looks too Japanese to be fully welcome in Peru, but she's too influenced by growing up in Peru to feel at home in Japan. She goes back through her memories in her dreams, collecting things that have meaning to her, trying to find her identity. When there's nothing left to collect and nowhere else to go, she ends her life.
