I like the plot so far I cant wait to find out what the father is up to

Fr and also I'm still wondering, why would they need semen? I understand using hair, pictures, saliva and stuff like that.. But semen??? Wha-!? Is he tryna curse his Grandchild??

That's what Im wondering why semen what is he trying to do

Big hunch maybe trying to take him to hell or offer him up to like a demon/evil god. Maybe thats why he keeps seeing hands all over him dragging him down and why there was a dead body??? Just a guess
