The nightclub stands for release, attraction and the wish to lose yourself in the crowd. Dream tradition also reads it as the part of life lived after dark, away from daytime rules.

My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
