I thought it was quite spot on, yes, as you said, as much as an NT can get it. That dreamlike wonder with which I sometimes walk, almost within my own mind, and notice things - it is very similar. Of course, not exactly like she portrayed it (my images definitely don't rotate...or blur...) but spotting that interesting leaf amongst hundreds of other leaves, focussing on the wheels of a car pulling away, staring in the rear view mirror, NOT noticing a lot of faces... that all rang a bell.
