The cottage stands for simplicity, cosiness and a slower way of life. Dream books read it as a longing to step away from noise and return to what is small, warm and enough.
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.
