If you have one eye then you see in two dimensions.
If you have two eyes you can overlay the images and see the depth of 3D.
If you have two 3D images overlaid then do you see in 4D?
This should be easy to construct.
Your intuition of higher dimensions can be trained, just as all senses are.
Technically, just by keeping your eyes open for a few seconds you are already seeing in 4D 😉
Haha, good point. I’m always trying to see in more dimensions, not just through time.
