Messy hair is read as thoughts in disarray or a life that feels a little out of hand. Some dream books see it more kindly, as relief at no longer having to look perfect.
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.
