A calf is young and inexperienced. Pertaining to your dream about a calf, you will encounter obstacles due to the same level of inexperience. Your peers will not overlook this issue if you do not improve in areas that contribute to the overall team where as currently you are holding yourself and others behind that associate with you. Shape up your knowledge and experience or ship out.
Dreaming of an apparition means you are longing to see the person that has influenced your life the most and need them to be there for you as you go through rough times. What would they do if they were you? How would they take on the obstacle and overcome it?
These apparitions are your subconscious attempting to guide you through the process of overcoming challenges.
If you dream of yourself missing an appointment, you are not focusing and paying enough attention to the details of your life. You fear that you are not achieving your goals and that there may be many obstacles in your way that hindered you from keeping that appointment. You should try to live up to the expectations that you want for yourself and not others around you. Even if you did miss that appointment in your current awake self, it does not mean that the world is going to end. Try to reschedule if possible.
Dreaming of a boulder means facing an obstacle that is beyond your expertise. While getting stuck in a bind is not what you foresee, it is important to ask your peers for help because this issue is not something that you can handle on your own. With help, your team can forcefully push the boulder or obstacles aside and move forward. It is a good day to think about gathering your team together to tackle the worlds issues head on.
