The eye of providence, set in a triangle, stands for a watchful higher presence. In a dream it is read as conscience, the feeling of being seen through, or a wider awareness opening up.
Has this come up in your dreams before? What was going on in your life then?
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.
