"I felt nothing" is perhaps the wrong expression. One time I had my vision strobing (as in I could turn my head and the picture in my mind would be like several images rather than a video) and ended walking around a music festival camping ground for hours.

What I meant was the experience did not really add much to how I thought about the world. I didn't have particularly meaningful conversations with anyone during that time. It didn't add perspective, which is kinda what I thought would happen.
