Anger is read as a boundary that was crossed and energy that was held back. Dream books take it as strength looking for a fair use. Shouting at someone you love is linked to tension that is hard to voice in waking life, while being the target of someone’s anger points to fear of conflict or disapproval. Uncontrolled rage is read as pressure building up for too long. Calmly expressing anger stands for healthy self-respect. It can help to notice who or what the anger was aimed at, because that often shows where the strain lies.

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.
