Being snowed in is traditionally read as a forced pause: the world outside goes quiet and you are left with your own company. Dream books link it to rest that was not chosen, or to feelings put on ice for a while.
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.
