Writers: in what way do you imagine your ideas before you write them out?

Sorry if the wording of the question is awkward, but I'm curious. When I'm thinking of ideas for a story, I tend to imagine it in my head like scenes from a movie. Do y'all do that too, or do you think of the words you're going to write? I wish I could do it like that, because it can be really difficult for me to put what I imagine into words a lot of the time. I want to write because I'm always thinking of new story ideas in my head, but I'm actually not that great with words.
