I’m starting to think I hallucinated this movie
Edit: I started to remember more as i described it and now im more confident it was definitely a movie. First i don’t even remember if it was a movie but that’s my best guess because i know i consumed it in one sitting (not a show) and I remember watching something not reading anything. Basically there’s these two girls, young, maybe kids maybe younger teens but no older, (I also think they didn’t get along in the beginning) they live on an island with a community, something tragic happens I don’t remember but I remember a lot of chaos and running and screaming and at one point one of the girls finds the other unconscious and blah blah somehow they’re left on the island, I don’t remember what happens after that until the end but basically they work together and become super close until the end when someone or some magical being (I don’t remember what their goal was but they did have a goal outside just survival) reveals the girl who was found unconscious on day one has been dead this whole time and the other girl was imagining her and basically the figment of girl 1 helped girl 2 to survive(like in fall) and she ends up accomplishing the goal (I think it was to get off the island and reunite with the others) and we see the already dead girl waving her off as she leaves the island and it’s bitter sweet. Im also 99% sure it was animated. Like i remember it being a kids movie which is weird bc kids movies rarely deal with death and if they do its not like this it’s like aw grandma is going to the happy place in the sky, not “youve been talking to a corpse of another child this whole time”but i swear it was a kids movie. Sorry for the run on sentence punctuation is hard 😔
Key points i know:
Must have two young girls who live on an island, must reveal at the end one has been dead the whole time.
(Open to the possibility it was an episode of something I saw too but I really remember it being a movie I even remember being a kid and going to see it in theaters with family or a friends (either my aunt or my friend and her mom)
