Many people live and die by the desk calendar these days. Ours is a time-conscious, time-driven culture. Most of us have more things to do on our schedules than we can comfortably manage. These pressures have created an environment where missing appointments and scheduled events is a constant threat.
Dreams to this effect are common. One of the trigger events for these dreams is the nagging fear that we may not get it all done as we should. Our anxiety about appearing competent to others is fragile and often assaulted in dreams.
Another interpretation of this dream is missing an opportunity. Life invites participation in more than could ever be accomplished. Every invitation comes with the promise that this event could change your life. The changes may include relationship or career rewards.
A final scenario revolves around fulfilling the relationship obligations that already exist in your life. In this case, dreams of missed appointments may be reminding you of personal obligations that already exist. You may be missing appointments as a sign that you are not fulfilling the needs of your spouse, family, or employer.
