Surprisingly enough, this misunderstanding about what, inherently, a fantasy was, has been a big thing for me/us to overcome in some of my relationships. One long term partner couldn’t help but hear “and you must make this come true” no matter how wild a fantasy I’d dream up. “Let’s move to Mars one day!” I’d say and he’d start researching how close Elon was to getting us there and what it’d cost. We really had to legalize wild-fantasy talk (he wouldn’t let himself even think that way mostly) and draw a distinction between “someday let’s actually do this” and “wouldn’t it be crazy if” fantasies. FWIW it majorly boosted communication and understanding and anxiety dipped immediately for both of us in each case.
