What does this dream mean? I felt something I never felt before in my life?

Im male and i was in a double bed (dont ask me why another male was in the bed- i cant remember to much about him) but as i turned round he was dragged away by the feet out of the bed with his arms trying to stop it.. then his body levitated in to the air.. and as I turned and looked up the I saw his body then the room began to turn bright white.. i did not know if this was some kind of evil spirit or even god who was about to get me.. so i turned away from this white light and my whole body felt something really strange (words cant describe it- but my skin began to tingle it was something out of this world) i then called out to god to save me.. and well the dream stopped. it was really strange. (I had been reading some leaflet about some christian who fell from a rooftop and cried out to god and he some how survived) i remembered that and did the same and I survived.
