Brake Lights Gone Crazy

My 94 MX-6 is doing something really weird. When I press on the brake pedal, the rear lights come on (the passenger side is dim) AND the front passenger side turn signal light comes on. Also, when I put on my right turn signal and press on the brakes, I get a fast signal like one of the lights is burnt out.

Anyone have any ideas on how I can trackt this problem down? Thanks!
