The monsters in the series have never had a set form. They appear differently to each person and there's no solid answer about what the fuck the otherworld even is. One of my favorite pet theories is that, since it's a projection of one's mental state, one who's wracked with guilt or resentment would naturally experience it in a hellish, hostile way, while the cult in 1 and 3 would've been free from all doubts and guilt, as every atrocity they committed was considered God's will. Going to the otherworld is a rapturous experience for them and carries a price for everyone else.
