I must confess I am brainwashed. Even worse, I do it to myself: with every shower I have clear water running across my skull for a lenghty period of time, because I truly believe this washes away the dross of everyday life.
Another way I wash my brain, or better yet my mind, is a collection of music that is evolving as my life does, but does feature for instance Ayreon, Within Temptation, and recently an album of the band named Conspiracy that very deeply resonated with me!
