If you put a 2d line in the first dimension, you get a dot. If you take a 3d cube in the second dimension, you get a square. If you put a 4D hypersphere into 3D space (like ours), it would appear as a normal sphere.
A square is just a collection of one dimensional points. A cube is a collection of two dimensional squares. A tesseract is a fouth dimensional shape that would be a collection of cubes. How is that even possible? How would you even visualize something with 3D objects as its outline?
I like imagining new ways to add dimension to a graph. Sure, you have X, Y, and Z. But what about using a shape to represent the fourth? How about the color of that shape as the fifth? The size as the sixth? The temperature as the seventh? I think about this when I try to sleep sometimes.
The craziest thing is the concept of the tenth dimension: which is every possible reality in every possible universe, and the whole thing just loops back around to bring represented as a single point of information.

Ok, I knew that the 4th dimension was like time but I had no idea about the Tesseract. Now I know why the blue cube in the Marvel Universe was called that and also that it held the space infinity stone. Clever.

Do you love me now?
