"I replayed the whole 8 Harry Potter movies in my mind, on repeat."
A few years ago, I attended a Vipassana meditation retreat. For 9 days, you don't get to follow the Noble Silence rule: no talking, not even intentional eye contacts. You are all on yourself with your chattering mind. The rule was lifted on the 10th day for transitioning back to normal life and allowing attendees to exchange experiences. And someone people can't stop talking.
Someone asked, "What do you think about while you meditate?" Everyone now knows: you simply can't stop thinking about stuff, even when you direct your attention to your breath, to your body sensations, or to whatever Goenka('s recording) taught, your mind drifts and you think about stuff. Most of the time you gloom about the past, other times you fantazise about the future.
An Indian guy, who said he'd attended the retreat a few times, said, "The first time I did this, I simply gave up and just replayed the whole 8 Harry Potter movies in my mind, on repeat."
Now this is the only thing I remember about that conversation. It's funny, the things one can remember or forget. I don't remember anything about what I thought about while meditating at the retreat, except that in the last few days, I could not stop swallowing and the sound of swallowing in the meditation hall was loud enough to make my neighbors start swallowing too.
