Skin is the boundary between you and the world, so tradition reads it as protection, sensitivity and how you present yourself. Its condition in the dream mirrors how exposed you feel.

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.
