Dreams involving bodily functions can often symbolize the release of emotions or stress. In your case, the presence of tiny frogs instead of feces may suggest that you are experiencing a situation where you feel overwhelmed by a multitude of small issues or anxieties. Frogs can also represent transformation, renewal, or feelings of being out of control.
The act of having diarrhea in your dream could indicate a need to let go of something that is troubling you or a fear of being unable to control certain aspects of your life. The frogs might symbolize the abundance of these feelings or thoughts that are "crawling" out, suggesting that they need to be acknowledged and addressed.
Consider reflecting on any current stressors or emotional burdens you might be facing. It could be helpful to find ways to express or release these feelings in a healthy manner. Engaging in mindfulness or talking to someone about your concerns may also provide clarity and relief.
