So.i used to dream.a lot about animals....not i don't.. Now its all humans...so is there any meaning?

In dreams every animal symbolizes something , every dream contains its own meaning and to know the meaning you have to connect all the parts with each other like where you were (is there any memory related to that place) and the people around you whom you know what you were talking about after that which animal grabbed your attention and the activity of that animal how the dream ended what were the emotions felt during that dream,etc it's a kind of heavy task to interpret your dream but at the end it worth it because you get to know about yourself at very deeper level, and the benefits you'll get after this are great feeling of self understanding and self love, and more lucid dreams ?

What did you do or watch back then, when you used to have animals dream?
