Crowd 
To dream that you are in a crowd hints that it is about time to make some space for yourself. This further suggests a need to be alone so you may ponder some issues you are facing and perhaps regain the strength to deal with your endeavors. Your dream may also mean you are 'going along with the crowd,' which refers to your conformist nature and weak sense of distinctiveness.
To see an unruly crowd in your dream represents the heavy burden being pressed on you by the people you interact with. This will continue to bring you much anxiety.
To see an orderly crowd in your dream indicates assured gladness, agreeable friends and opportunities for advancement.
Mass 
A dream of mass symbolizes a connection to a set of religious principles.
To dream of going to mass and feeling a great relief represents your need to desire solace in a church or a friend or family member.
Say if you have never attended a Catholic mass before except in your dream, your subconscious may be borrowing symbolism in order to construct a space in which to express spiritual curiosity.
Circle 
To dream of a circle represents your life quest for excellence, unity, and fulfillment. On the other hand, it may also signify that you are having difficulties resolving a certain issue. You cannot seem to come to a satisfactory answer. You may feel as if you are at a stagnant period in your life; you aren't moving forward as planned.
To see circles within circles implies that you have built up strong walls that are very difficult for anyone to penetrate. Perhaps you should consider allowing others to see your true personality. It may also reinforce the idea that you are traveling in a continuous path and are not able to achieve your goals.
To see an imperfect circle in your dream is an indication that you may experience hardship and hurdles as you strive to reach your objectives. Be assured that your efforts will be rewarded.
To see a circle with a cross represents the world and your environment. This may lead you down a path of spiritual discovery.
Audience 
To dream that you are in front of an audience indicates that your thoughts and behavior are being closely scrutinized. It may also represent anxieties and apprehensions that you hold about displaying your innermost emotions to others.
Agoraphobia 
If you dream about yourself suffering from agoraphobia, it indicates presence of anxiety or panic in your waking life. It could be hinting that you're unwilling to meet new people or open up to others.
Alternatively, it may indicate an underlying uneasiness with your surroundings whether it is at work or in a social setting.
