How can you explain the similarities and differences in the dreams of adolescents of different generations?

In different years and eras, a certain type of worldview is dominant. It is this type that will influence the formation of goals and dreams in adolescents of a certain generation. If in the previous era values of a more spiritual order prevailed, then dreams corresponded to them. In modern times, the worldview has moved towards materialism, and therefore dreams have become focused on consumerism.
But there is one thing in common in the dreams of all teenagers – this is that they all strive for something, want to achieve something and assert themselves.
