Now do this put-the-text-back-together activity.
This is the text (if you need help).
An expert thinks she has unlocked the secret of what dogs dream about. A psychologist at Harvard Medical School did research into dog dreams. She concluded that dogs dream about their owners. She also said dog dreams were similar to those humans have: "Humans dream about the same things they're interested in by day….There's no reason to think animals are any different….It's likely your dog is dreaming of your face, your smell and of pleasing or annoying you." The psychologist advised pet owners to give their pets "happy daytime experiences" so they have nice dreams.
The psychologist said there is no way of knowing what dogs see in their dreams. Research isn't close to solving that mystery with human dreams. The research is based on the fact that dogs have a sleep cycle like the human cycle. This includes a period of activity called REM (Rapid Eye Movement). This is the part of sleeping when humans dream. The psychologist said: "That certainly makes it the best guess that other mammals are dreaming too." Dogs may also move about while they are asleep because they are acting out their dreams. Their legs move in a running motion in their sleep.
Back to the dog dreams lesson.
