A sandstorm blinds and disorients, so it stands for confusion and stress that make it hard to see the way. Dream books read sheltering from it as waiting for clarity to return.
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.
