After sitting for about 2 minutes, everything started increasing in brightness, to a point where I could not even look
at the
rocks because they were completely white and too bright. The same happened with the environment like the sky, trees, etc. Basically, everything was too bright to look at. By this point, I could not talk, move, see, or think really. After staying this way for about 2-3 minutes it started ramping down generally fast and everything went to normal brightness.
