A child car seat stands for protection and responsibility for someone who cannot yet look after themselves. Dream books read it as care, caution and the weight of keeping another person safe along the way.
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.
