I don't have severe sensory issues (meaning, ones that stop me functioning on a daily basis), but do have some.
I like plenty of light - in fact I need it and don't like sitting in a dark room, except at night to sleep, then I don't want any light in the room whatsoever, so I have the window blacked out. I like natural light as opposed to artificial light - I don't like bright points of light in my eyes, so always have artificial lighting behind me when I'm working, and have my screen light turned right down, too. I dislike intensely blue LED lights - they just seem intolerably bright to me, but don't seem to affect other people as much.
Unless I give permission, I hate to be touched. I hate people tapping my shoulder to catch my attention, or this social touching which is very common here, even among strangers - touching my arm. I don't need it and don't see the necessity for it, and never, ever touch other people. For other people, this social touching seems necessary and instinctive, but not for me!
Also sound - I hate always hated high pitched sounds and found them painful and unbearably loud, always had difficulty following a conversation in a noisy environment, or when there are more than one person speaking at once. Always prefered quiet environments. Now I have hyperacusis and things are even worse.
