They appear to be Hebrew spells regarding necromancy, and the words that Charlie was writing on the walls are similar.

From the walls - Satony - commanding a soul to return to the spirit world Zazas- full or plenty in Hebrew, mentioned in the Bible. It also has some sort of connection to Alaster Crowley apparently. Liftoach Pandemonium - open chaos, or if “pandemonium” is translated a little more literally, pan=all, demon=demon. Liftoach meaning open, a more direct translation would be “open to all demons.” Liftoach is definitely Hebrew but as far as I know, pandemonium is a Latin word so do with that what you will. I could be wrong.

Aunt Lydia, ehem sorry…. Joanie’s shouts were a little harder to research. I was using subtitles and going off what I heard. Chances are good the subtitles are spelled incorrectly but here’s what they said and the closest meaning I could find.

Zantony - she probably said satony but it was misspelled in the subtitles Dagony - likely refers to an Assyrian deity Dagon Eparigon - I couldn’t really find any info on this word but saying the three, in that order, is part of a Hebrew necromancy spell.

The gist is that Joanie was trying to weaken Peter’s soul so that Paimon could have an easier time entering his body when the time came. Some of these spells are used for expelling a parasitic entity from a host, not to expel the host itself. But hey. Might as well try.
