No. If anything, it's an intensely personal reaction to mundane, mildly unpleasant events (misplacing something, receiving criticism). While no fan of loud noises, he does not seem to have problems with crowds, nor would I characterize him as hyper-observant. He's much more apt to be in his own world, oblivious and slow to react to his environment.
