2006 Dodge Dakota wipers, windshield & visibility problems

Windshield wipers turn on unexpectedly while the vehicle is moving obscuring the driver's vision which could lead to a loss of control or crash.

I noticed that the windshiled wipers would come on by it self, as time went on the dashboard lights and stereo would go off for about 4 seconds; later the horn would blow and the wipe fluid would squirt, then I would get a aweful shock when I touch the gear shifter. All these occur whenever I start the truck after sitting for more than 7 hours, then at any given time while driving with at least 4-5 times and ever increasing as mileage travelling.
