If I could add on to Tiberius' analogy:
Imagine bacteria on a piece of paper. They are so small that they would think the universe is 2D, but then they would see anomalies like imperfections in the paper (e.g. small bumps) because it's not perfectly flat. This would suggest to them that there's another dimension.
I believe that we are the same. We can't comprehend the "next" dimension (if there's one) because we are limited somehow in the same way the bacteria are. As for anomalies in this universe... well I don't think there's evidence of that sort so far.
