To dream of applause represents praise, enthusiasm, or appreciation. It may also point to an overwhelming sense of approval or a “pat on the head” from others.
Applause may also reflect an overwhelming feeling of relief that something good has finally happened. Being appreciative of good luck that affects a number of areas of your life.
Negatively, applause in a dream may reflect a self-centered or naive belief that other people are impressed with an accomplishment you’ve made. Being impressed with yourself for having done something difficult, or giving yourself a “pat on the back.” It could also reflect jealousy of someone else getting more recognition or appreciation than you did. A narcissistic view of your accomplishments being impressive and important.
Example: A woman dreamed of people clapping for her. In waking life she had broken up with her boyfriend and took a risky chance to call him again to try to get back together. She ended up getting back together with him. She felt that all her friends were surprised by her breakup and glad to see get back together. The applause in the dream may have reflected her tendency to care too much about the approval of others in having her relationship and not enough on the problems with the relationship itself.
