A red card is read as being sent off — excluded for crossing a line. Dream books link it to fear of rejection, or to a boundary you feel you have overstepped.
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.
