In folk tradition the chimney sweep and the brush are old luck figures, read as clearing soot so warmth can rise freely. The dream stands for cleaning out what blocks your inner fire.
Where in your waking life have you met something like this lately?
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.
