You should definitely google the meaning of your dream! Who knows -
Google might be a big help!
But this dream doesn't have to have anything to do with your friends, it could also have something to do with you, your love life or your dream of having kids. It could also show the fear of being cheated on or the relationship between you and your friend! I hope you're going to find out if it has a meaning and of course what the meaning is! Good luck with that - I hope you'll keep us posted :)
