Water Element Holding Personality of the “Astral Self”

To TAO Honchos:

can anyone corroberate water system holding the personality of the “astral” self?

example: next time you go to scratch your head without thinking while figuring something out– same process, BUT

your are in conversation and water element begins contracting/absorbing (feels sexual and unconsious, about liek scratching yourself) and whole body responds including full thought sometimes heard directly by others within their own minds…

why do people scratch their heads when they decide they need to figure something out (like a primate figuring it’s own brain out)? and why is it so unconsious? some would say pure inherited animal instince, but apparently the astral self is inhabiting that same space..
