In modern dreams the clock or watch sometimes has the meaning of a reminder of our temporality. Sometime before death people dream, for instance, that their watch is broken beyond repair.
Von Franz argues that the clock in modern dreams operates on two symbolic registers: as a reminder of mortal temporality (the broken watch presaging death) and, in other dream contexts, as a symbol of the Self representing a time-bound yet transcendent world order.
