Gravity stands for what keeps you grounded: responsibilities, ties and the weight of the real. Feeling it grow heavier is read as burden, and feeling it loosen as release.
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.
