I want to be a dog also a strange dream

Ive been having these dreams for a couple of years now. Ive always had the urge and want to be a dog. If im in a store I would want to just become a dog and run around on all fours. Its the truth im not going to lie. Id love to be a dog. Everytime i think about it i get an urge, want, feel, sensation, passion to just become a dog. This feel is usually in my chest. Going back onto the topic of the dream ive been having these dreams im a black german shepard dog, always tge same dog. Im usualky tgat dog in a senario that i had the previous day. For example, on a bus home or in a class room with friends. Some night i wake up and im chewing my pillow or im barking or growling. Once i actually ripped up my pillow case and had to buy a new one!

Is this dream normal? And is this want and urge normal? Ive had this need and want my whole life. Im serious as far back as i can remember ive wanted to be a dog.

Thanks looking forward to hearing your input.
