Staying with a host family is read as being welcomed into a home not your own. Dream books link it to adaptation, gratitude and learning new ways of living.

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.
