Heaven is traditionally read as peace, reward and reunion — the hope that what was good is not lost. Dreams of it often carry relief, longing for someone gone, or a wish to rise above present worries. Meeting loved ones there is linked to grief and comfort, while being turned away at the gates points to guilt or fear of not being good enough. Bright light and calm are read as inner peace. Every faith pictures it in its own way, and dream books read the image with respect for that. It can help to notice what kind of peace you are longing for.

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.
