In Yoruba tradition an abiku is a spirit child thought to come and go between worlds, and the name carries the grief of loss. In dreams it is read symbolically as fear of losing what you love, or as a cycle of hope and loss that you wish would end.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
