Lava is read as intense emotion in motion — destructive, but also creating new land as it cools. Dream books link it to passion and anger that reshape whatever they touch. Lava creeping toward you is usually read as a feeling you can no longer keep at a distance, and crossing it safely as getting through a heated situation intact. Glowing lava seen at night is often tied to fascination with your own strength or desire. Hardened, cooled lava stands for a storm of feeling that has passed and left solid ground behind. It can help to ask where your energy is running hot right now.
When this appeared in your dream, what were you feeling?
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.
