The bedroom is the most private room of the house, so dream books tie it to intimacy, rest and the self you show only to those closest. Who else is in it often says more than the room itself.
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.
