Life support is read as something kept going by outside effort alone. Dream books link it to a relationship, plan or habit you are holding on to, and to the hard question of whether it can stand on its own.
Where in your waking life have you met something like this lately?
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.
