A sudden jolt out of sleep is read as the mind letting go too fast and catching itself. Dream books link it to a busy, watchful state that will not quite settle.
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.
