My red traffic light turned green then a second later back to red?

Today I was at a stop light and then I saw it turned green so I started to accelerate. The next thing I knew, I was looking back up at the light halfway through the intersection and it was red again. There was no yellow, It just went from red to green to red again all within a few seconds. I looked behind me and no other cars went so I'm a little confused as to why the light did that. My passenger in the other seat also said she saw it turn green and then it was red again. I basically ran a red light because of this.
