All kinds a stuff we *can* decode I believe, and sometimes happen into spontaneously. Bit like looking at one of those 3D piccies where there is a 'moment' where the image resolves into a perceptual eureka. Multiple layers of stuff going on. Usual human perception partakes (moreso these days it seems, if we don't discount the stories of our ancestors & other cultures as 'mere superstition') of a the fraction essential to our survival, but not all of it. I'd love (well not very) to know what my Cats are staring at some nights (a Ghost Road runs through my house...).
