Mind may operate at high frequencies when used appropriately. Just like dolphins' sonar.
Subconscious stores some frequencies willy-nilly, so you can return to them on a later date. To better understand it, let’s take music as an example.
Music, it’s either something you enjoy or process. Linkin Park, The Rasmus, Evanescence is the music that makes the link between your subconscious and conscious. Crawling [child abuse], In The Shadows [unplugging from the system], Bring Me To Life [waking up to what we’ve become] are some songs you have to see through at some point. Because this world is full of shit (as George Carlin would say) and to get rid of it, firstly you have to know it.
