We were in a rush, either walking or in a car. I was able to observe it nonetheless.
It wasn't actually the very end of the rainbow, more like towards the end but close up. The actual end disappeared into some plants. We must have been in a rush because I was desperately trying to get the other people I was with to look at it but they were arguing about something. By the time I had finally got their attention we had already past it and that's when I woke up.
It was really flat, transparent. Just like the colours of the rainbow but translucent and on a much larger scale (because it was so close), there was a lot of purple and blue and it was like dancing lights. It reminded me a little bit of a fruit roll-up.
