Is it normal to act like a dinosaur?

For some reason, I believe that in some way I am or like to act like a dinosaur or dragon. I am interested in dinosaurs/dragons. When I was younger I would play this kind of game that I was there "pet dinosaur or dragon" I enjoyed it very much. When I am acting like a dinosaur, it tends to be like a velociraptor. As those are my favorite dinosaurs. Sometimes when I'm on the field alone I snap and growl and go into a position of a raptor. I run around and pretend to hunt. I would whisper to myself like a documentary of what I was doing. I thought that it was most amusing to myself. I would jump onto things and roam dinosaur like and make growling and weird sounds. Sometimes I still do it. Same with dragons. I would like answers please!
