A robbery is traditionally read as feeling that something is being taken by force — time, energy, a sense of safety. Dream books ask what felt threatened. Being robbed in the street is read as feeling exposed or unprotected in public life; at home as a violation of your inner space. Losing money is taken as worry about worth or resources, while losing something sentimental is read as fear of losing memories or identity. Being the robber is read as wanting something you feel you cannot get fairly. Catching the robber is read as reclaiming your strength. It can help to ask who or what drains you without asking.
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.
