It seems most of these downward spiraling people are from Asian countries like India, Pakistan, China, etc... as there was only one Caucasian man in the grocery store spiraling.
There is a good chance these people seeing something and then going into an uncontrollable SPIRAL could be from the Chinese SINOPEC injection and it is possible that the Caucasian guy is or was in a country that offered the SINOPEC INJECTION.
Half of the whole world lives in Asia so there are a lot of people over there as well.
