I like the "hidden sense" JamesLove.

Its interesting that in our times it seems common that we believe we generally understand something about reality. Interesting that many great minds are the first to point out how little we know. I vote for a few more senses.

SWIM wonders how his senses developed in hyperspace can be awakened fully in normal space as he notes natural occurrence of DMT in the human ... he also wonders if that even makes any sense ... or if it needs to.
