The sloth moves slowly and hangs on calmly, so it stands for rest, patience and the right to take your time. Dream books also read it as a gentle nudge about putting things off.
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.
