A wormhole is a shortcut through space, read as the wish to skip a long process and arrive at once. It can also stand for sudden leaps between memories or parts of life.
Has this come up in your dreams before? What was going on in your life then?
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.
