Brainilessness 

A lack of presence of mind; a state of mind where a person’s marbles can be heard rattling around in his head just before he mislays them; a point in a person’s thinking where mindfulness does not naturally occur.

I can see by your present demeanour that, at the present time, you are in a state of brainilessness, whereby your mind has gone for a walk on the wild side without your knowledge or the consent of your intellect.
