Being grounded as a punishment is read as feeling restricted by authority. Dream books see it as guilt, or as being kept from something until a lesson is learned.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
