I will try to describe it the best i can. 
I can hear voice in my head my own voice that's normal I think but when ever I try to make a decision like I would like to go there and suddenly like there will be 5 or 6 of my own voice talking to me about how it can go wrong if I go there or how it can go very good for me Or i should stay home and all this thought come at the same time and it doesn't stop until I decided what to do. When I am sad and depressed they will cheer me on like thing will get batter and you are over thinking everything or is suicide a good option(not gonna committee suicid never don't worry) they argues among them selves like I am a voice like them deciding what to do but they some time mess me up too.I have many examples but you get the idea they all say a deferent outcome for me just like a video game.
Hope you understand this if not sorry i don't know how to describe it
