Dreams often reflect important issues. Think of motives, interests, talents, but also current challenges or unresolved issues. People who frequently tell each other their dreams, show a lot of themselves this way. There are no false sentiments, no intellectual pretensions, or any other smoke screens, it all stays real. I think that this is special.
In a social sense there is relatively little experience with dream groups. I suspect that dreams are useful for resolving conflicts, because they can quickly point to the real issues, in a way that shows to all parties what really is at stake. Dreams are also very good for creative inspiration, which means there could be more fun social applications as well.
