Neuroimaging research has found that psilocybin increases self-inhibition in visual brain regions and enhances top-down connectivity, leading to vivid, internally generated visual imagery with eyes closed.
Yesterday, we hung a painting that I gifted to my partner that has a highly psychedelic vibe to it (coincidentally rather than on purpose, I think). I told my partner that it'd be great to view on mushrooms (she tried them with me for the first time six months ago; I'm quite seasoned). A plan was made.
