Can you make it to the end of a shopping centre?
That's the question the UK's National Autistic Society asks in this video, which aims to show the sensory overload a boy with autism experiences in an environment that people without autism often handle easily.
The lights are blinding, the sounds are deafening and the images are scary as the boy tries to process the overload of sensory information.
"I'm not naughty -- I'm autistic," is the message the charity features in its campaign to help people understand autism.
