A fire station is readiness: help waiting for the alarm. Tradition reads it as your capacity to deal with a crisis, and as the wish for someone to come quickly when things flare up.
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.
