Dreaming of being in a group of lemmings often symbolizes a feeling of being swept along by the crowd or societal pressures. The lemmings represent a tendency to follow others without questioning, which could suggest that you may be feeling influenced by external factors in your waking life.

The voice you followed could represent a strong influence or desire that is pulling you in a certain direction. Since you approached it slowly and carefully, this indicates that you are exercising caution and perhaps discernment in how you navigate decisions or influences in your life.

The water covering the floor can symbolize emotions or the subconscious. Water often represents feelings, and the presence of a hole could represent potential pitfalls or dangers that might not be immediately apparent. Your sadness for the lemmings that fell may reflect your concern for those who blindly follow others without considering the consequences, possibly including people around you who may be making risky choices.

Overall, your dream suggests a balance between following your desires or influences while also exercising caution and awareness of potential risks. It encourages you to be mindful of your own path and the decisions you make in relation to others.
