We actually kinda do perceive a fourth dimension: time. Sure, we infer it from our memories and come up with cause and effect relationships to help us understand it. But we do know it's there.
Okay, sure, but the question still remains, how do you know that there isn't some 5th dimension for some random objects.
I think that's one of the theories for explaining dark matter (i personally like the idea because it can also possibly address why gravity seems to be so much weaker of a fundamental force, but i'm a chemist, not a physicist, so take that with a grain of salt).
