hi this mite sound strange but last night i had a strange dream basically i was talking to someone or something in my dream but could not understand what they or it was saying all i no is at the time in my dream i mean the earth was shaking and it felt like whoever or what ever i was talking to was extremely evil in nature, but its not what they are that disturbs me so much although i would like to find out what they are.
firstly its what they said is more important basically the person or being said and i quote" filius es luciferi" what does that mean i think it mite be Latin but am not sure if it is what does it translate to in English and what does it mean?
