The thoughts carry on thinking that they are not a part of themselves. Kidding aside: it has to do with a sense of being misunderstood, alone, aloof, not fitting in, etc. Being in the world but not of it. The system that has us all trapped….alienating all of us from even ourselves….those are the bad thoughts, Theo. It’s not all bad but we all share not knowing for sure what is on the other side of the curtain.
