A corridor that goes on with no end is traditionally a picture of a transition that feels drawn out. You know you are moving, but the next room — the next stage — refuses to arrive.

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.
