Very scary and confusing dream..again?

Ok,please read all of this so you can full understand the dream I had.Ok,last night in my dream,i was inside my school track area were people on track run.I was running with other people i didnt know for some reason.Then,we all stopped sudenly and sat down.A VERY bright light from the sky came down toward the floor beneath me.Then,the floor opend up and their I saw was fire and and people burning to crisp.I was freaking out so bad,I stepped backed and ran away as far as I could,but then someone spoke from the sky(which is most obviously god)saying,"You shall not descend onto this earth",then closed the hole in which I saw fire and people burning.After that,I was in a VERY high class bar with very unordinary designes.People were laughing and talking with each other and all seemed to pleasent.Then,some women came up to me saying"Are you read?".I said,"am i ready for what?".She then laughed and dragged me into some room that was very dark designed with sorrow and sad feeling.She made me sit on this hostpital bed and put needles into my viens.She took some blood and put it into this pen.She then started to murmer a languge I have not known of,it sounded like a very ancient languge.She then took out a scroll and said to me,"Sign your name here."I was confused and asked,"what is this?".She then said,"Remember,your sacraficing your sould to lucifer like us so he can descend onto this earth and destory all that is holy and take over paradise."At that moment,I went crazy because I am a christian and her saying that made me very scared and angry.I hit her and tried to get out of the bed but she came ontop of me with the pen which she had put my blood inside of and tried to kill me with it!I got the pen and stuck it in her throat.After that moment,A very dark voice started to scream and started to roar.Then I blacked out completely and It felt like I really blacked out in real life as if i had been shot with a need to put me to sleep.When I woke up I was with my family sitting on a table at some restruant that I cannot recocnize.When we were sitting,some person came and sat next to our table.When I turned to look at them,they looked right into my eyes and smiled.That is when my dream ended.What does this dream mean?
