I guess ABBA wasn't the only demonic prophesy that came out of Sweden. PSALM 21 has actual demons.

While looking into Swedish zombie film ZON 261 I saw that the production company had already made another horror feature that was released last week in Sweden, Psalm 21. A religious horror story about a priest haunted by horrible dreams about his dead mother and then finds out that his estranged father, also a priest, has died under strange circumstances in a small village in the Northern part of the country. Traveling there he finds out just how strange these circumstances were and to spice things up, he encounters some demonic presence there as well.
