The dream page asks for the dream in your own words and a few optional tags. It then looks for ordinary words — river, door, horse, exam — in a short dictionary written for Tao Reading. The matches are cultural notes, not a codebook that converts a night into a future.
The explanation that follows is allowed to use two things: what you wrote, and the entries that matched. It is not allowed to diagnose, to prescribe, or to tell you what will happen. A dream of falling is not a medical finding. A dream of a funeral is not a prediction. The page says this in the result, not only in the footer.
If you are signed in, the dream can be saved with your history so you can export or delete it. It is not sent to the analytics log. Anonymous readings stay in the response and are not filed under an account.
