## Dr Strange and multidimensional mental structures

Mindmaps and mental palaces are essentially two-dimensional structures. This allows for simple navigation: linear and lateral itineraries.  99% of the time this is more than enough.

Intuition takes many forms, but what is it exactly? Why do genius scientists talk about mysterious forces? Do we really need the supernatural or there are more plausible explanations?
