1998 Honda Accord Electrical System went Haywire

I was on my way home and I noticed that my car radio light seemed to be flickering on and off. All of a sudden my engine revved up high and I had lost all acceleration. My lights dimed to nothing. My engine kept going strong, I just didn't have any acceleration for about 10 seconds. It kicked back in and I went for about another block or so when the same thing happend. This time I had to put my car all the way down into 1st gear since no other gear seemed to work. I cut my headlights down to hazzards to conserve power and made it home in first gear. The whole time my engine had plenty of power. Never cut out even once. I turned the car off at home and went to restart it immediately. It clicked like the battery was dead. What is going on with the car?
