In today's physics, the cutting edge theories require multiple spacial

In today's physics, the cutting edge theories require multiple spacial dimensions to work. Bosonic String Theory, for instance, requires 26 dimensions, while the five basic types of String Theory seem to need at least 11 dimensions. How can a person mentally visualize these extra spacial dimensions? Do they only exist as complex mathematical Calabi-Yau shapes, that only Hawking can imagine, or is there a more simple way a person can envision a sixth dimension, etc?
