Waking up screaming and another dream with a reoccuring theme of an orange muscle car.

Within the past few months every now and then I seem to be waking up screaming for some reason. I don't really seem to know why. I do remember the first time it ever happened was many years ago when my family still lived together. I remember the dream and it involved having my brain transplanted into a girl's body. I was laying in a hospital bed with my family around me and I remember someone saying "is he still as tall as he was?" Someone replied with something to effect of  "No Tanya was only 5'7" After that I looked into a mirror and I saw that I was a skinny, lighter skinned African American girl. I was so startled that I woke up screaming and in turn startled my cat Marvin that I had at the time.

Today around 6:30am I woke up screaming and then went back to bed. It's interesting that I fell back asleep and had yet another dream that seemed like a reoccurring theme of a teenage boy driving an orange muscle car speeding through the neighborhood. This time I was I actually able to talk to him about it. I recognized the grill was of an AMC Eagle but the body was like a Ford Falcon. I asked him what kind of engine he had in it and I was confused that he didn't know. After that I told him to slow down driving through the neighborhood and he agreed.
