Hope Iīm not intruding but I think most descrptions of shared dreams are naive and false because both the dream environment and the dream characters are obviously mind-created buh this does not mean I donīt believe it could happen. If we assume every experience is mind-created as some philosophical schools believe then anything can be explained. But at my present state of perception, any shared experience will manifest very subtly as shared thoughts, opinions, desires, synchronicity, affinity, insights and so on.
