Does Animal dream?

Yes, animals dream. Researchers Dr. Matthew Wilson and Kenway Louie at the Massachusetts Institute of Technology selected four lucky rats. They implanted micro-electrodes into the hippocampus, the region of the brain associated with memory. Then they monitored the firing patterns of the neurons hooked up to micro-electrodes.The patterns were the same whether the rat was dreaming about running around on a track or actually running around on a track. In fact, by just looking at the patterns, the scientists could tell whether the creature was dreaming about running or just sitting around. So why do animals dream? Probably to re-live and learn from experience.

Hmm animal dream. From the research it seems like they are dreaming survival technique.
