so first of all i want to say, that i study goetia, (a magic system thay works with infernals, also know as daemons or demons.)) and glasya lasbolas it's one of the infernals, i don't have contact with them, but just for context.
so for the nightmare, there was alot of random things so i gotta list just the important parts.
that was a woman that came to work at my home, and she died os misterious causes, some time after that, my wardrobe door started to open alone a lot, i got out of the bedroom and when i came back, that was a bizaree creature that looks like babadook, but around his eyes was just meat, he came closer to me with a maniac smile and bloody but large and thin hands, saying he wanted to kill me, i beg him to not do him, snd he gave me five days, and what should i do within this 5 days? doubt, if him was real, if all of that was real, then when he was going out, i asked him (idk why) if was him opening the door before he appeared, he said no, that was glasya lasbolas. (the dameon i mentioned) then, i runned to a fashion departament, and asked my witch friend. (i know her in real life) for rituals, i was told a lot of things, mainly to burn a rose, i shearcrd trought he place then wen i finally founded, i went to my mom, and the creature left some thing wrote on my mom, (i don't remember what) and then i said "i hope he's sympatic with you" cause was a gersl chaos around everyone in the nightmare.
that's all, sorry for the long text, and sorry for any mistake, english isn't my first language.
