Assume that is what you mean...
My biggest accomplsihment so far with magic was when I was getting kidnapped (long story), and I was able to take complete control of my body. It was like my subconscious mind was completely open to my conscious mind. I was able to control all of my bodily functions that are normally locked off from you. I could literally stop feeling anything, turn off my ability to hear/see/smell/touch, stop my heart, release chemicals, anything that your body can pretty much do. (It was AMAZING) Anyways, I used that ability to practically kill myself since I was being kidnapped and had no desire to go along with my kidnappers. (I figured dying was better then being kidnapped and I could always come back reincarnated) But in the moment before I died, my life literally flashed before me... I saw my memories of the world, my thoughts, and my loved ones... and I knew that I still had a job to help others in this world and to protect my siblings from going through the same experiences I did. So I relinquished my power over my body (well mostly) and proceeded with the kidnapping. I did hower turn off the feelings of hunger, thirst, pain, my sense of time and induced sleep though to make things better. But yeah, that's the reason why our bodies don't want us controlling that stuff if you've ever wondered... And, ever since that day I've always had the ability to control my body,(mostly).
