The dreamer is in the lead and jumps a ditch of water, just clearing it. The others fall into the ditch. The young man who told me this dream was a cautious, introverted type and rather afraid of adventure.
Jung uses the shared dream image of a ditch to demonstrate that the psychological significance of a symbol is entirely conditioned by the dreamer’s life-position — the same obstacle signifies opposite things for the cautious young man and the bold old invalid.
