We can perceive more than three dimensions; in physics the world in which we live is modeled as space-time, a four-dimensional place. I don't know about you, but I'm pretty sure I have the ability to perceive the passage of time.
One might also reasonably argue that we can perceive more than three dimensions in other physical contexts as well; it comes down to semantics.
For example, the phase space of a rigid body in classical mechanics is six-dimensional, and we can certainly watch rigid bodies move around, so perhaps one would call that "perceiving" more than three dimensions.
As another example, states of quantum systems are often modeled as being elements of infinite-dimensional spaces (Hilbert spaces), and we observe quantum systems all the time, so perhaps one would call that "perceiving" more than three dimensions.
In short, it all depends on what you mean by "perceive".
