The ask is overwhelming…but it also isn’t, haha! The thing is the answers can be long, they can be philosophical, they can fill books!! But, heh, they really don’t have to in my experience. I’ll break them down and show you what I mean:
How can I start writing fan fics?: You’re probably gonna hate the simplicity of this answer but…just start writing! Seriously, just start writing them. Even if the first dozen you hate and never post, you’re still writing fanfic! It’s the only way to start and the only way to get better.
How can I start getting ideas of what to write?: Another simpler than you’d think answer: You said you daydream “like way too much” (no such thing unless you’re causing yourself/others harm due to lack of focus lol) so that tells me you’re already getting ideas. Topics, imaginings, characters, etc…just start with those daydreams, my friend, Afraid you’ll forget them when the time comes to write? Jot them down in a notebook. And all those fanfics you’ve been reading? Use them as a jumping off point! Don’t copy them or take OCs (of course) but maybe you’d like to add more to an idea that a fic explored or have a new twist on some character or relationship mentioned. (Think “I don’t agree with this headcanon, I’ll a story with MY headcanon” or “oh wow, I didn’t think of that, I’ll write a whole piece to explore it!” and so on.) …And this works just as well with anything fandom you may have read/discussed/seen.
How do I start writing what I’ve envisioned in my head?: Again…just start writing, haha! Once the basics are down you can go back to add details to make the picture in your head clearer on the page. Then edit. Edit. Edit. Clear out what stops making sense, add more of what’ll help clarify that picture in your head. …If you can, find a Beta – aka editor – to help in the beginning and always, always, read aloud yourself before posting (if you decide to post).
…If you’re already getting compliments on non-fiction then you know how to write. The only difference with fiction is, well, it’s made up. So just start finding inspiration everywhere/anywhere you can – daydreams, music, film, TV, other writings (fanfic or otherwise), even nonfiction things! – write down your ideas, and then start playing. In the end, to get really good at anything, it’s a matter of practice so…
Write, play, challenge yourself, and don’t ever give up!!
((Hope this helps you, Anon, and anyone else out there who may be curious!!))
