Dreams often reflect our subconscious thoughts, feelings, and experiences. In your dream, the classmates from your training course making fun of you could symbolize feelings of insecurity or vulnerability that you might have experienced during that time. This might indicate that you felt judged or misunderstood by your peers, which can lead to feelings of isolation.

The subtle nature of their teasing suggests that these feelings could be tied to more nuanced social dynamics, perhaps indicating a fear of being undermined or not being taken seriously. The act of them putting small objects in your clothes might represent how these negative feelings or criticisms can feel invasive and bothersome, affecting your sense of self.

Your reaction in the dream, feeling entitled to despise them and identifying with extremist views, could indicate a desire to assert your identity and beliefs strongly, particularly in the face of perceived ridicule or judgment. This aspect of the dream might illustrate an internal struggle with how you view yourself in relation to others, especially regarding your political beliefs.

Overall, this dream could be prompting you to explore feelings of acceptance, belonging, and how you navigate social dynamics, especially in environments where you may feel judged. It might be helpful to reflect on whether there are any lingering feelings from your training course that need to be addressed and how they relate to your current beliefs and interactions with others.
