What Am I?

Recently I've been a deer, along with a dog. I don't feel alone in my head, there are at least two other animals in here with me. Recently, my body's convinced me that there are fawns in my stomach, that I'm pregnant with them. It's usually one during the day, but there are about three or four at nighttime. It's then I get lightheaded and tired and feel them in me. The worst part is that what my stomach feels doesnt correspond to my hand...my stomach is too small when I touch it, but i can feel them inside me. It's all very confusing...Sometimes I talk to nothing there, like when I spoke to one of my classmates and scoffed at kittens.

There are other animals, other things, in my head, but they do much besides make decisions for me...
