Can someone explain these dreams?

If you did something bad recently, your subconcious could be thinking you're going to hell... Or it could be metaphorical and you have "demons" you need to face, like if you have a problem with someone and you need to confront them about it. If all of these are about your best friend, you may have a problem with them? Or you could just be having some weird nightmares because of a movie you saw. If any of those are correct, there you go. But that is pretty creepy.
