It makes perfect sense. Thanks, @michellesamson.
I did think the style was familiar.
I watched Mama years ago, when it came out. Did not remember exactly the concept art for the scary creatures.
I just checked and, yes, the scary woman with sharp claws on scary child's shoulders much have come from there.
Do you watch a lot of horror movies?
I stopped watching them, precisely because fragmented images make their way to our dreams and there's no fun in that. Also, horror movies became quite formulaic and predictable, relying more on noise and gore than in actual scary stories.
Thanks a lot for commenting
