Was I glitching?

I fell asleep one afternoon. I startled awake without anything startling me. I did not dream, not that I remember. For a moment after I woke up, I did not know I am an existing being. I lay there, in error, like a machine that did not start up properly. Then, I was overwhelmed by everything: sense of the surrounding, sense of time, sense of self but not sense of purpose. The first thing that came to mind, almost instinctively, was a question, "why am I back?"

There was a second that I can feel the void in my chest.

I wished I had faded out.
