I found this reference to the symbol and Oneiric Paradox. Whatever it is I think I have found it!
My master was always saying that this symbol shall be cut into fossil wood when the moon is three nights old. Then your dreams will come true. But I also found some references to demons. Oh my Lord! What did you have done to this clergyman! This cannot be real, this cannot be real!
I am afraid, even Abraham is behaving strange these days.
