Same here, but I thought it was smells, or dust, or some logical explanation. but this maybe more logical the more I think of it. I get it from people too. but not everyone, and not everyplace. interesting...very interesting. some perfumes on some people are fine, and on others ...eeew. same with air fresheners, in some places, they NEVER smell fresh. They seem to make it worse.
sometimes, I get so dizzy I think I will crash to the ground. interesting.
