Helping someone in a dream is read as compassion and the wish to be useful. Dream books ask whether the help was welcome, or a way of avoiding your own needs.
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.
