nightmare

i need help interpreting my dream it was very very weird and scary
i was in a room with about 10 to 15 people and my friend was layin down in a bed wrapped around many blankets and the group of people told me to not sit down on the bed because it was possesed by the devil and i said forget the devil he isnt doing nothing to me and i still sat down and i yelled you see nothing and then next thing i got possesed by the devil and i started to rock back n forth and i was killing my friend that was layin down in the bed with my mind tho and then the group of people pulled me off the bed and thats when i snaped out of it and i woke up

and the next day i told my friend about the dream i had and he said that same nite i had that dream he had a dream that the devil was killin him resemblin to mine but in my dream it was me killing him
