4D space isn’t something that we can intuitively imagine because it’s not a part of our sensory perception.
There are various ways to think about it though. For example, imagine you need to graph something in 4 dimensions. If you know what a 3D plot looks like, imagine you add color to the data being plotted. The color is the 4th dimension.
Another way to visualize it in your mind is by imagining a cube. The cube is 3D. Now imagine there are infinitely many more cubes to its left and right (like a number line, but made of cubes instead of numbers), that’s 4D space.
If the 4th dimension were time, you can imagine each 3D cube as one specific moment in time.
