Through the old saying about being “in the doghouse”, dream books link it to feeling shut out after a mistake. It can also stand for loyalty and the small, plain shelter given to someone who guards you.
When this appeared in your dream, what were you feeling?
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.
