Dream about failing is your ability to process emotions quickly. You need to be more responsive to others, instead of just sitting back and waiting for things to happen. You are unable to let go of the past. It is an indication for some overwhelming task or emotion that you are going through in your life. You need to eat a more healthy diet.
Failing dream points to undeveloped aspects of yourself that you are ignoring or refusing to confront. You are losing sight of your ambitions and goals. You are not going the distance in some task. Your dream is an admonition for some fears or anxieties about femininity (if you are female) and your masculinity (if you are male). You are experiencing difficulties in getting your thoughts and feelings across.
If you dreamt about failing:
You may be confused by your heart. It may be extremely frustrating when you can’t keep a tight rein on your emotions. This internal conflict is a signal that there’s a lesson to learn. Perhaps your heart knows something that your conscious mind hasn’t yet realized.
