A trivet protects the table from something too hot to handle. Tradition reads it as a buffer that lets you deal with a heated matter without getting burned.
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.
