The video below is created by the National Autistic Society simulates the sensory sensitivities experienced by some people who are in the Autism spectrum. I must emphasize that each individual with Autism is unique, therefore this video does not represent the experience of each and every person with Autism. However, it offers a window for us to experience what it could be like.
I hope that this video will help you understand Autism a little bit more.
