A range hood draws away smoke and steam, so dream books read it as clearing the air after heated moments. It stands for venting what builds up during daily pressures.
Has this come up in your dreams before? What was going on in your life then?
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.
