This is strange after all! This place doesn't look like the village I know at all.

Where does this stairway even lead to!?

That's something strange you've said there.

This place is the core of your consciousness, known as your "instincts". There is no bottom.

May it be that woman holding her child or that old lady dying alone from before, they're all your memories as a human being leading up to who you are now. Possibly past incarnates of him

There are countless number of your cell's doors, up to the span of your memory as a human being. Referring to the biological cell.
