That blurring also sometimes takes place during the changes of adolescence.
I remember there was a time when I was 12 to about 19 that I could tell whether some one was dead or alive just by looking at photographs. We tested it a few times. I was always right.
It eventually went away. I researched it and it is not an unusual phenomenon to have young adolescents be temporarily gifted with some sort of second sight.
I do not have one airy fairy bone in my body.
