      We usually describe the universe as 4 dimensional – 3 dimensions of space, and 1 of time! But if you’re talking about 4 spatial dimensions, it’s very hard to imagine and I struggle with it too! Carl Sagan made a very interesting video on the 4 dimensional hypercube (also called a tesseract), I would look it up!

      Conceptually, I understand the problem with trying to visualise a 4-d world; trust me I battle with the visual aspect constantly. But yeah, the world is 4-dimensional but only 3 of them are spatial as Jordan explained!
