A social worker in a dream is read as outside help, oversight or someone checking on how things really are at home. Dream books link it to the need for support, or to the fear of being judged.
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.
