Being recorded on video stands for a moment fixed and replayable, open to later review. Tradition reads it as the wish to preserve something, or the unease of being documented.
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.
