i mentioned "dancing is just stimming with music" recently in earshot of someone and this was a revelatory concept, so if u needed that express permission to get wiggly when ur feelin a groove: there it is
you can learn to do a kind of dance if you like, you can certainly cultivate it as an art and a skill to be shared with others. but you can (and should!) just move ur body for yourself. unless ur trying to do dance competitions or smth, nobody worth concerning urself with is gonna be judging
not once has my day been worsened by seeing some rando deciding to dance their way through a part of the day, or at a party where someone's doin some kinda funky thing that feels right to them. even if it is unskillful, awkward, uncoordinated: that's a voluntary show of passion. cherish these
