Pajamas stand for rest, safety and the private, unguarded self. Wearing them in public is a classic dream image, read as feeling unready or exposed in a waking situation.
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.
