I agree, I managed to develop similar visualization abilities through several months of visualization training. You should also look into mnemonics, it is closely tied with the ability to visualize and a masonic memory books has a two page chapter in wich they imply that it has something to do with the third eye (without explicitly saying it, as the book is for the "uninitiated")

Pic related is from "Solomon's Memory Palace: A Freemason's Guide to the Ancient Art of Memoria Verborum", this page is the only page in the chapter titled the "eye". What could he possibly have meant by this?
