Kay so I think Kaya is semi-possessed by a spirit and maybe her in utero sibling is possessed as well so that why she sees her as a 'spectre'. That or it will be a still-birth

ugh, and that is why we stay tf AWAY if you hear no sounds in the woods/forest. both the normal (hungry/rabid predator) and the paranormal (malevolent beings) will mess. you. up.

and another one bites the dust

i have a nonsense theory about her gramps kid, it seems she have 2 daughter,1 is kaya's mother and one i can't see. in the family pic kaya's mothe had dull eyes and look real suspicious, i think her grandma had done smt that it now connect to her daughter (grandma even said: my...( i don't remember her name)) it could be someone related to her
