Why did i here satans voice in my dream?

Last night I had a dream, It was about some paranormal investigators and myself investigating a mystery about a parking lot, they had put out some kind of guiding system that appeared like some medium sized ipod headphones, as we were about to reach a corner we saw a shadow we thought we were getting action, so we followed it, It appeared to be a lady, white haired, she directed herself to me and started speaking in a language unknown like a satanic ritual kind of speech, she continued this until a darker deeper devilish voice came in unison with hers. The guy that was in the group jumped on her and we went to see what had happened, we looked at her , and her face became like a normal woman. I then appear in a hotel room with the same people i had done the investigation with, so i was scared to sleep in the room because of the experience and i asked the man if i culd sleep in the room with him. Before that he said let me bless the room, got a metal rod and smoke and started praying, i looked to the corner of my eye the chair started to move like one of those computer chairs i told the man he kept praying, then all of a sudden the chair was pushed against him, and a long wooden hanger for like jeys and stuff flew of the wall, i started praying and yeling " in the name of jesus i repell you" like my mother thought me. And i started hitting the ground of the room where this was happening and what i heard was "i dont believe in jesus nothing you can do can make me leave" and i woke up. What can this mean? please give me your opinion? what i care about most is the satanic voice and the ritual language.
