I have a feeling that with this video, like a few others that I have seen, the the maker seeks to put a wide range of possible experiences in the video, or tries to represent every possible sensory experience, where in reality, an autistic person will typically experience some, but not all... for example, the sound coming from the lighting. Some autistic people do experience this, but not all. I can indeed hear some lighting and electical equipment buzzing (as can NTs), but not every light is going to do this for me. Others might be more sensitive than me. and have this issue continually. My sensory sensitivities are mild in comparison to others, but no less real - I get the jumbling up of sounds, making it difficult for me to follow a TV show or a conversation with background music or sound as so well demonstrated in the video, and details, various small sounds and details kind of leap out at me and grab my attention, often causing me distress if there's too much going on, I but I don't, or rarely, have sensory integration issues - visual or aural distortion, blurring or blanking out that some people get, or at least, I don't experience it exactly as shown on the video. If I'm overloaded, I just don't process (I don't 'see' or 'hear', don't process what I see and hear).
This next one is accurate for me. It is very well-made: it shows how details - visual information and sound can leap out at you, and how small children in particular find it difficult to cope with. This is indeed how I experience a mall. For me, as an adult, it's doable: I wear headphones and listen to music in the mall, I can stop and sit down, and just look at the floor for a while, if I feel I'm getting over loaded, but a small child can't do this.
This next one is accurate for me, too, and also shows how I experience the sound coming from lights, different to the TV one. It also shows how I experience glare coming from lights or sunlight. it also shows how it can be ok for a while, but at some point it becomes too much and everything intensifies and becomes unbearable - I get this too, but without the blurred vision. That doesn't happen - or I'm unaware of it happening, because if I'm overloaded I don't process anything full stop - unless this is what the blurred vison is supposed to represent. I feel very uncomfortable and stressed, and need to get out of there. I also sometimes get a kind of 'unreal' feeling when my senses are flooded, things seem surreal and not real, it's difficult to explain.
