Can an Object Be Two Dimensional?

Felix: Can an object be two dimensions, like the object itself only exists in two dimensions? Or, you know, maybe it exists in a subset of our dimensions, or does it mean that it's just like superten? I think the answeris yes to all of those. Felix: It's hard to imagine an object having four dimensions in our three d space. But why can't an object have two dimensions, be essentially only x and y, and have no height, right to be a super thin slice? Is that possible to have a lower dimensional object in our universe?
