 I put it all together weeks later when I remembered the DEET spill from several months earlier. Pesticides&amp;#x2F;insecticides, in my experience at least, can induce those symptoms, lol - maybe the mosquito spraying was a little heavy by the hotel? And now I hope I don&amp;#x27;t have brain damage, thanks internet.</text></item></parent_chain><comment><author>dboreham</author><text>I had an experience when I was a hardware engineer working in a lab that had been converted from previously being a machine room (for mainframes: raised floors, closed ventilation system). I was cleaning a prototype board with trichlorotrifluoroethane (or something similar -- whatever the solvent du jour was back then). The board had the typical green FR4 or Brobimer solder mask film. While engaged in this task I saw a little green dragon emerge from the board, chuckle, then blow a small flame from its snout. The whole thing was entirely realistic. The only thing that made me realize it wasn&amp;#x27;t real is I was pretty sure dragons don&amp;#x27;t exist.</text></comment>

I hope you&amp;#x27;ll be fine, because people have done much worse!</text></comment>
