Twilight state

Today I did a 23 minute Muse session in the rainforest. I started calm, with multiple birds landing around me. I was counting my breaths with 1, 2. At first I was counting at the end of the breath. For some reason, that was causing me to think too much, it didn't feel natural and so I switched to counting at the beginning of the breath. Minor change and it made a huge difference. Even though the end of one breath and the beginning of the next breath is only milliseconds apart, it made a big difference. About 8 minutes in, I went into a twilight state like right before falling asleep. I wasn't tired as it was 11 AM in the morning. I don't recall much from the next few minutes and when I came out of it, the storm was much stronger and there were no birds. I started focusing on my breathing again and was able to recover and the birds starting landing again. Kind of surprising to me that during the twilight state, my mind would be so active. Pretty cool experience and one of my longer Muse sessions. I will have to do more of these long sessions and see what happens.
