A webcam stands for being seen and watched, often more than you would like. Dream books read it as self-consciousness about your image, or as concern about privacy and exposure.
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.
