I think some animals can dream and think about something that they want. Garfield is a cat, he was dreaming and he stayed near his owner ( JON ). If his owner got up, he will hit Garfield because Garfield disturbed his sleeping. I think some animals and some pets dream about themselves or they can think about other things like " do they have enough food to eat?" or " do their owners be nice to them? "and some other dreams. While Garfield was dreaming, he didn't know his react or what he said to his owner. Garfield dreamed and told his owner that he was hungry last night and he was eating millions of flowers. He told his owner like that I think he wanted his owner to feed him lots of food. Three kinds of animals that I would like to describe about their dream are dogs, rabbits, deers.
I think dogs usually dream that if their owner tell them to look after the house and bark while there is someone who isn't his owner and then he fall asleep. When his owner come back, does his owner hit him? does his owner feed him the food?
About rabbits, I think they can dream and afraid that their owner forget that they can't drink water. If their owner confuse to put water for them to drink they will die because all rabbits can drink only dew.
The last one is deer. Deers usually afraid that if they walk to the river in order to drink the water will they meet tigers? Can they run to escape from those wild animals?
These are the dreams that some animals think about. They dream about these because of their feeling. They can dream about something because they really want those things or they feel worry about those things that is why it keeps in their mind and become the dream for them.
