Dreaming about a crowd means that one has self-doubt of following the right path in one’s life to achieve their goals, instead they have relented to follow what everyone else is doing such as partying and socializing.
When a crowd is cheering for you in a dream, it can symbolize you gaining greater prominence and recognition. It implies that you have a big social life close to home with lots of friends who will provide comfort and warmth. It also manifests when crowds are present like during gatherings at a game or event.
A dream about a lack of a crowd cheering indicates that the person will face life struggles where they have lost the attention of others.
