I'm a boy who got reincarnated as a girl?! How'd that Happen?!

The continuance of 'Reincarnated As a Dwarf.' Hi there, the names Aaron Kakashi, I'm just your average teenage boy. I go to orange star high school and am not exactly a straight A student, but still I make my way through the years as they go bye. Well anyway, it was just another normal day for me. Well except for the fact that it was snowing and the roads were completely iced.
"Man I swear why'd it have to snow today if all days?" I questioned myself angrily as I continued to walk to school. I watched as the light signal turned red, which meant I could start waking across. I was walking across the icy road carefully, so I wouldn't slip. I kept walking and was about to reach the end of the cross walk, when suddenly I noticed a bright light out of the corner of my eye. In curiosity, I turned to my right to see that it was a car. It was coming straight for me. I tried to run, but before I could escape, I was hit by the car. I felt the hard metal hood come into impact with my body as I hit the cold icy ground. I felt my soul slipping away as I saw a bright light start appearing. It enveloped me, but before I knew it, I was in water. Everywhere, nothing but water. I tried talking to see I could talk.
"Hello, is anybody there?" I asked in curiosity. Then I heard a voice in the darkness answer me. It came into view. I saw it was a bright blue light.
"Hello there. It seems, you are different from all the others." The blue bright light said as I looked at it in awe.
