What do I if my horn all of sudden just goes on? on 2000 Dodge Neon

I had my vehicle parked at my stall and all of a sudden my neighbor came and told me my horn is going off. Even when I was driving, I accidently went over a pot hole and my horn starts going off again, I had to hit my horn several times in order for stop. Can you help?

Sounds like the horn (button) module has deteriorated and collasped to the point of making the contacts close the horn circuit and sound the horn. It needs to be removed from steering wheel to test.
