Ah yes; it's a bit of a challenge, but it is possible to dance with her without her getting lost in her thoughts! Girls that are naturally more gifted with romance may have an easier time accomplishing this than others, but with enough mycelium anything is possible (...I think!)
(If you're reloading to retry the dance choice and keep rolling the same number, I've noticed that sometimes the engine we use (Renpy) isn't actually all that random. This could also contribute to getting the same result over and over like that~)
