La La Land. I had just been unexpectedly dumped by my anchor partner a few days earlier. Crashed at another partners place and did a bunch of mushrooms, they put the movie on without thinking just trying to fill the time to keep me distracted. The movie about two people having a very sweet relationship then breaking up and not getting back together again was maybe a poor choice lol. We had to stop it part way through so I could ground myself but after a while I did end up pulling it together enough to finish the movie (with some crying breaks here and there). 10/10, would mushroom and watch again. Helped me process tbh, after I knew what I was getting into, very emotionally draining on me though.
Never tried shrooms yet, but had a similar experience with Amelie. Just after the break up I held myself okay, like a functional adult, but when there was a scene where Amelie felt like she's imagining things and he'd never come for her, I teared the hell out of me, nearly vomited my guts out from the sudden strike of sadness. Doubt I'd recomend it in an altered state of mind tho - the movie is already wicked. Yet, it's very, very sweet. If you'd come around it, feel free to write me back about how it felt, or maybe do a post here on the fediverse.
