Accelerator Problem: 1999 Dodge Stratus ES

My car is a Dodge Stratus SE 1999. This is a very weird situation. After backing out of a parking stall, I happened to bump into a telephone pole behind me, not very hard, and as I put it in drive and stepped on the accelerator something went terribly wrong and the car accelerated forward extremely fast and I had no control. It was as if the car was gaining speed on its own, and I was hitting the brakes yet it gained momentum on its own and I smashed the front of the car, etc. Ran into a house in fact. No alcohol involved. I subsequently read that putting the car in neutral would be the thing to do perhaps but it happened so quickly I just hit the brakes by instinct, but it didn't matter. I was wondering if someone might help me out with this. Could it have been a computer malfunction of some kind? (that's how it acted -- as I said it was out of my control...as if I was speeding on ice and pumping the brakes, that's how it felt). Or perhaps an accelerator problem...? This has never happened before. I had the car towed last night and it's sitting in my driveway. I haven't driven it yet (this happened last night). No citations from the police or anything. Thanks!
