The tundra is read as emotional coolness or isolation, a stretch of life where little seems to grow. It can also speak of endurance in harsh conditions.
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.
