Drifting Away: The Silent Battle of Mind and Body

I was sitting in class while the teacher explained something, but I couldn't understand—not because it was difficult, but because my mind wasn't there. I wasn't thinking about possible futures as I usually do, nor was I dwelling on regrets or potential alternatives. Instead, I found myself in a fictional world where I could see everything from above. Everyone appeared small, and as time passed, I felt myself drifting further and further away.

I could no longer hear anything clearly, just indistinct mumbling. I saw myself smiling and looking attentive, even nodding occasionally to show the teacher I was paying attention. But why? Why was my body operating on autopilot? When did this system activate? Does it happen when I'm with friends and family? When I am happy with them, am I truly happy?

What if I don't return to my body? What will happen if the autopilot is more convenient than me? And what if it stays forever?
