Reminds me of the Tralfamadorians from Slaughterhouse-Five. They are able to see in four dimensions so humans appear as fetuses at one end of the four-dimensional person and dying at the other end.

Interesting concept. I wonder if it's compared with spatial 3D space, then how large would the 4th dimension of time be if it were to fit the timeline of a human lifespan

A natural interpretation leads to time being very large and us moving very very fast through it.

It's convenient to model our movement through space-time as occurring at the speed of light. Thus, the faster we move in space, the slower we move in time all the while the length of our space-time velocity vector is invariably c. We can then imagine 1 second of time being interchangeable with 299,792,458m.

...which means that a Tralfamadorian would see an average human as a 6*10^17 meters long snake.
