Struck By God

This dream had a few different parts, but one part really stood out to me. I was with a bunch of other people that I didn't recognize, but I think they were supposed to be my coworkers. We had finished all or our work and were about to leave for the night, when in the distance beautiful rays of light started appearing from behind a cloud. All of a sudden, rays of light started shooting at us, killing anyone they hit. We all started running around trying to avoid the rays. Somehow I knew that the rays were coming from God, and as I ran I prayed "God please dont kill me, I believe in you I promise." After a few minutes I was the only person left, and I knew I'd survived.
Now here is the strange part -- I dont believe in God. So what could a dream like this mean?
