Don't say much about personality, continue your dream. When you met your friend, you passed a school. The school represents a place, a kind of knowledge and wisdom. Will "school" become a barrier between you? Because your relationship is unclear, I don't want to speculate here. Get to know friends through school, and friends remind you that the rain boots on your left foot are missing. Boots are paired and worn on your feet. How can you disappear unconsciously? This is a lack. Finally, I found my bag, but it was gone. If the lack is deeper, it is not satisfactory, and it should also be a reflection of the real life state. Boots can be understood here as walking with oneself. A bag can be understood as your own burden or responsibility. In your dream, you didn't say whether you found it, but the foreshadowing of rain appeared ahead, a kind of harassment-thunder. My friends also came to my side, asking me to avoid the reminder that is actually my subconscious, so as to avoid this kind of harassment. Finally, my friend was hit, and this friend was my initial search target.
To tell the truth, I still don't quite understand this dream. What does this initial goal have to do with dissatisfaction? Maybe only dreamers understand.
