Taking Sour Food and Feeding It
Interpreters have reported that whoever dreams of taking sour food and feeding it to someone else might indicate that the one being fed will hear similar unpleasant words. If the dreamer themselves ate the sour food, they might suffer from sadness or illness. However, if they patiently ate it and thanked God for it, they might achieve relief.
