Oh yes. I should take out stock in Downy, as everything has to be soft. My son has social anxiety, sensory issues on all fronts, but can drive a car and has a sky high IQ. He's at the upper edge. Is your brother a sensitive to the paranormal things? I've found many are.Oh yes definitely. Different things other than sound bother him though, like certain smells and tastes. He is extremely picky with some things and not others. He is very detailed with certain things. It's interesting with the different sides of the spectrum.
