A pillar is read as strength, support and steadiness — often a person others lean on. A crumbling pillar stands for doubt about something you have long relied on.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
