YES, that’s the word. I want to write immersive fiction. I think I must have expressed myself poorly in earlier posts though because I really don’t think every detail needs to be based in reality… the things I’m thinking of would just be the cherry on top of the imagination cake. I prefer fairly sparse writing.What you're actually concerned with is making your writing immersive.
If I may say so, if that's the case, you're focusing on the wrong things. As writers, we don't just rely on memory, especially in fiction. We face that challenge when writing situations or places we've never been in before, and I imagine that every fiction writer has been there. What we have to do is use our memories and imaginations. Imagine the feelings of being there, and imagine the things you can see. Then describe *that*.
If I want to write an immersive description of a space casino, I'll imagine what it looks like (probably based on the casinos I've been in), and some space elements, like a gas giant out of the window or something and try to write that. I will add in any details I can think of that will make it seem more exotic and more sci-fi, and then only if it adds to the setting. For example, if I want to add some aliens in, I'll base that on, maybe, the cantina at Mos Eisley. I don't need to take my real experiences of being in a casino to make it immersive. If any such experiences come to me, and I think they'll add to the writing, I can put them in, but they're not necessary.
In general, develop your writing craft by often *not* writing based on your physical experiences. That way, you don't have to rely on it. Don't sweat the fact that you can't remember every detail. Readers aren't going to be interested in all of it anyway.
It’s very interesting you suggest actively not writing from experience. I hadn’t ever thought of it from that angle, but it’s an approach I should try. (Obviously all the sci-fi and space-based concepts I come up with are not from experience, but I never approached it that way.) Is that something you learned from experience or did you pick that idea up somewhere? (= if you have books please recommend them. I’m in heavy study mode right now.)
