Needing an alibi is read as feeling suspected and having to prove your innocence. Dream books link it to guilt, earned or not, and to the wish to have your account believed.
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.
