A sudden replay of a past scene is read as a memory still looking for its place. Dream books treat it as the mind returning to finish sorting something.
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.
