the reasons for the customs of the telling of feelings and the sharing of dreams

At first look, the sharing ritual looks like constructive family time. As we examine it, we begin to sense some disturbing things. The family sharing seems more like indoctrination. The Elders use this family time as a way for parents to spy on their kids as well as kids to spy on their parents. Both parents and kids are required to report any abnormalities. Parents are required to instill the values of the community. Dreamtelling seems like an extension of sharing of feelings only that it reveals the subconscious thoughts rather than the conscious ones.
