General Meanings:

Desire to belong to group If the dreamer is a member in an association in his dream, possibly in a sports club, he emphasizes the right of every people to belong to a group of their own choice. The association may indicate the need for contact with like-minded and wise people. But also this dream gives a sign to follow more his own head, not to listen to others, as well as not to adapt to every fashion.

Psychologically:

Not ready The dreamer is not mature psychologically to be a member of a group, when he can not make a decision to enter or not the association in the dream. If he stands in his dream in the middle of a crowd of people, then this may show that the dreamer desires for self-expression.

Spiritually:

Well-ordered rituals which are common in the life of the association, can be an important part of spiritual awareness.

* Please, see meaning of club.
