Cellulite in a dream is read as worry about being judged on appearance and the gap between real bodies and ideals. It mirrors self-criticism more than anything else.
Where in your waking life have you met something like this lately?
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.
