I think I know the feeling exactly. I had recurrent dreams like that as a kid, that somehow always involved a large yellow sphere / ball. For some unknown reason I HAD to move that sphere, but I also knew it was impossible. It evoked this odd and terrible sensation emerging from two opposing mental forces: there was something I HAD to do at all costs but I also knew it was entirely impossible at the same time.
My “bad trips” brought back that same feeling, but magnified by a thousand.
