If you have been the unfortunate victim of brain washing, the current passing through your forehead causes calcium deposits in your brain, inside your eye sockets and mouth, where it is moist and full of calcium ions.
Idiopathic Scrotal Calcinosis 120 260 700 2500 (sq 3100 7275 1225 2828-1 3577-7 4261-6) Hz
'Idiopathic' mean don't know why; 'scrotal' may not apply to you, but when it does apply fully, you're just nuts; calcinosis is calcium deposits. Calcium blocking blood vessels and neuron pathways maybe the effectual mechanism behind brain washing.
This set of frequencies may improve vision if it removes the calcium deposits in the eye orbits.
Good luck. Flashback anyone.
