Screaming is read as feeling that needs a way out — fear, anger or pain that has been held in. A scream with no sound is a classic dream, traditionally about not being heard or not daring to speak up. Hearing someone else scream is linked to worry for them or to a part of you calling for attention. Screaming in fear points to an anxiety close to the surface, and screaming in anger to a boundary crossed. Waking from your own scream is read as release. It can help to ask what you have wanted to say loudly but kept quiet.
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.
