Who turned on the light?

I decided to go to bed earlier than usual last night...that being before 3am preferably. I came offline by 1am and after reading a bit I took off the bed lamb, covered with my blanket and was asleep shortly after 2am. About an hour later I become aware... not of anything really, just the fact that I was aware. I was cold... shivering. I was still wrapped from chin to toe in my blanket yet I was shivering. My skin was super sensitive... it hurt just to feel. It was like having a high fever. I was aware of all this... and began twisting and turning wrapping myself more into a fetal position, clenching my pillows...anything to not feel so cold and sensitive. I remember turning from side to side, moaning even, but not being able to awake. I was fighting now to open my eyes but I was still trapped in that semi conscious state. The last thing I remember was me tossing and turning with the blanket wrapped around me, then just blank! Nothing. The perfect equivalent to deep sleep. And as if no time had passed, or maybe an eternity, I woke up with a sensation of rising out of water and finally being able to breath. There was an overwhelming bright light keeping me from opening my eyes, but when I did, I realized it was my bed head florescent lamp, on, and shining directly on me, inches away. I reached above and turned it off and rolled over. There I found my blanket tossed to the side, albeit neatly, perfectly stretched out from the head to the foot of the bed in a rippled fold. I reached over to my cell phone, put it on and saw that it was now 6:20am. How did the light come on? when? who? I knew I took it off, I remember taking it off. All these questions raced through my mind, all colliding with each other in a blurry mess appropriate for the state of thinking upon waking. I felt as if I had jus woken from medicated sleep. The kind where you dream nothing and remember nothing. I sat on the edge of the bed and unconsciously moved my hand to an itch on my knee. Looking down, I noticed there was a little scrape, a bump and some dried blood. Then a flash of a similar incident came to me...maybe from last night, maybe from night before... but I remembered waking in the middle of the night scratching an itch thinking it was a mosquito bite. It was raised in a most peculiar fashion but the seduction of sleep was more than enough for me to succumb to a non-thinking state again. Shaking the image, I got up, went to the bathroom, walked back to bed looking at the lamp in wonder once again, and just went back to sleep...for 7 more hours.
