A henna night is traditionally a gathering of women before a wedding, full of song and blessing. In dreams it is read as farewell to one stage, care from your circle and the beauty of ritual.
When this appeared in your dream, what were you feeling?
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.
