Trippy Skull Vision

Anyone who’s taken psychedelics LSD, psilocybin, mescaline, mainly, [or, for some, even high doses of marijuana] are probably familiar with the highly symmetrical geometric patterns one tends to see. They’re often the harbingers of the psychedelic 'come-up'. The fact that they show up so reliably, though, raises some questions. Pretty much everyone, regardless of their experience or expectations, sees them, which means it’s likely that something quite fundamental is happening in our brains. We haven’t fully teased out exactly what’s happening yet, but one popular theory is that the neurons in the brain’s visual cortex are firing at random — normally, they only fire in response to seeing lines or edges. To put it simply: what you’re seeing is the actual layout of your own neurons. A pretty trippy concept, isn't it?
