研究发现狗狗会梦见主人
An expert believes she has detected the secret of what dogs dream about. Dr Deirdre Barrett, a psychologist(心理学家) at Harvard Medical School, did research into dog dreams and said that, among other things, dogs dream about their owners.
Dr Barrett said canine(犬的) dreams were comparable to those we have. She said, “Humans dream about the same things they’re interested in by day. There’s no reason to think animals are any different. Since dogs are generally very attached(依恋) to their human owners, it’s likely that your dog is dreaming of your face, your smell and of pleasing or annoying you.” The psychologist even advised pet owners to give their pets happy daytime experiences to make sure they have nice dreams.
Dr Barrett stated that there is no way of knowing for certain what dogs see when they dream. Research isn’t even close to finding that mystery with human dreams. The results are according to the fact that canines and other mammals(哺乳动物) have a sleep cycle(周期) that is similar to the human sleep cycle. This includes a period of activity called REM (Rapid Eye Movement), which is the part of the sleep cycle when humans dream. She said, “That certainly makes it the best guess that other mammals are dreaming too.”
Dr Barrett also explained the reason why dogs move their legs while they are asleep. She said they are probably acting out their dreams, so their legs move in a running motion(运动) in their sleep.
