Looks kinda like a particular dream sequence from Vinland Saga. Not exactly what the rest of the show is, but if this image intrigues you I bet you’d like season 1. Season 2 takes a huge tonal shift, I still like it but if you decide to watch just know it won’t be the same as season 1 at all. (This dream is in season 2 but is sort of a reflection on the change itself.)
