Offering something to a ritual fire is traditionally read as release and purification. Dream books link it to letting go of what is finished so that an intention can rise like smoke.

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.
