Fingernails are read as both protection and presentation — a small shield and a small display. Well-kept, polished nails point to self-care and attention to the image you show others, while neglected or dirty ones suggest stress showing at the edges. Long nails are read as a wish to keep others at a distance, or to be noticed. Broken nails are linked to small daily frustrations and to losing grip on minor matters. Biting your nails in a dream is usually taken as nervousness that has nowhere else to go.
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.
