Yeah, I get the sensory overload thing too, along with the sensitive hearing (particularly with certain sounds - clicking or smacking sounds are the worst for me), a really sensitive nose (accused of hallucinating odors that I KNOW are real) and tongue (can taste individual minerals in some foods). I've read that the hyperacute senses is a known Lyme symptom. My guess is it is from the neurotoxins the Lyme bacteria produce that happen to irritate the part of the brain or nerves associated with the sense that is hyperacute, but I don't know this for sure.
