Harry's New Pants

Harry can’t escape the ads. Billboards call to him by name, his job has been stolen by AI, even his therapist works for the company. When he accepts a free neural implant promising peace of mind, the noise fades, but something worse takes its place. Harry discovers that his dreams are being hijacked to sell him products. With the help of a black hat hacker and a mysterious resistance, he learns he can fight back against a vast corporate network that's manipulating reality itself. As the lines blur between waking and dreaming, Harry must sort it all out, with his very existence hanging in the balance.  (Originally puiblished in Bewildering Stories.)
