Help,the most scariest nightmare?

Ok this is very serious and I don't want people thinking they are funny or smart giving me one plain answer that does not make any sense.Last night I had the most terrifying nightmare I had in my life.I am 15 years old.Please read all of this I know it is long.Last night in my dream,I was infront of this very scary and dark house.I entered it knowing it is just a dream an i dont usualy have nightmares anymore.I went into this room and their was a man with a black robe sitting on a very satanic bed with the baphoment(symbol of satan) as the sheets.I was very scared and confused of what was happening and I am a christian!The man which I could not see hit face clearly said he was the devil and want me to explore the room.Some force drove me to open a pitch black closet.As I opened it it was the most deepest feeling I had in any dream.When I opened the closet their was a bookshelf about 2 feet long and the under space were you put cloths had nothing in it.All the books were black and one had humans marked on it.As I reached to open it the cover had a pyramid and an eye on top of it looking at me.When I opened it it showed all the names of human people and red marks on them.The book was about 1 feet tall.Then from that moment I knew this was the book the devil used to put the names of the people who are in hell.From that moment I was scared out of my mind about to have a heart attack and this seemed so very real!The next thing I picked from the closet was a round red bag with a rubber band closing it.I opend the red bag and their came out a human head and from that moment I screamed my lungs out and turned around to see a poster of a man.I did research and the man in the poster was Adam Weishaupt,the founder of some secret society called the illuminati.He was looking at me smiling.He had very very sharp eyes and his left eye was red.From that moment his face turned into a demon and his face was the most scariest face I have seen in my entire life,I have not seen a face as demonic as his turned into and I was freaked on the verg of death!The,the bibles words spoke to me inside my mind in my dream were I read said that lucifer shall be thrown inside the lake of fire when the world ocmes to an end.I screamed and closed my eyes and said"Lucifer is temporal and he shall be thrown in the lake of fire when the world comes to an end"and when I opened it the same poster with Adam Weishaupt(founder of the illumanati)was still their,but he was sad.I think that my words from the bible made him very upset.It was a very strange atmosphere while i was in this dream,it was dark,cold,scary,and full of upset emotions.What did this dream mean?I am very scared and I am a christian and the devil and the illumanati is not very pleasent seeing in my dream.I woke up screaming and sweating after it was done.
