Help, Car is clicking at me without the key.. .will not start with the key

I was sitting in my 1999 dodge caravan, and it started to make a clicking noise… I removed the key from the ignition and the clicking noise continued… it seems to come from the fuses by my left foot.



I have tryied to start my car and nothing happens, but the clicking stops if I push my foot on the break.



I popped the hood and the fuse box by the battery was also clicking… but that has since stopped.



I tryied one more time to start the car, only difference is that the speedo thinks it is going 120mph.



I think this happened once before and it just needed a new battery… is that possible?

My husband replaced the battery and that fixed everything.
