The hummingbird hovers and drinks from flowers, so it is read as joy, lightness and savouring sweetness while it lasts. Its tireless wings also stand for energy that is spent very fast.

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.
