2008 Dodge Grand Caravan wipers, windshield & visibility problems

While my vehicle was parked at a campground, I click my key fob to unlock the door and the rear windshield wiper started going off. Tried to start the vehicle and it would not start, no lights nothing completely dead. The wiper eventually stopped. A few hours later, still parked with no keys in it, the windshield wiper fluid and wipers started after I clicked the unlock button on the key fob again. The fluid kept shooting until it ran out of fluid.

I was picking up my daughter and opened the door and the horn started blowing, the wipers were going, and the window washer fluid was spraying out. It finally stopped and was fine but has happened multiple times since one time even when I was driving down the rd and now I've had to disconnect the battery but now I can't connect it again because it won't stop going crazy like that.
