The trick (and it’s not easy) is moving from a vantage point of: “object is compressing due to compression of spacetime” towards “object has the appearance of compression because spacetime geometry is moving in a direction (dimension) we can’t perceive”.
The Flatlanders story is fantastic for this one.
