Questions and no answers

Sam drove the 25 miles to his parents home in about half an hour the whole trip asking himself what had happened but no matter how hard he tried nothing came to him he remembered running home from the library getting home and going to bed right away so what happened for his body to get stronger he decided not to think about it cause it was giving him a headache. He used his key to open the door and stepped into the kitchen it was empty of anybody he wondered if anybody was there it wouldn't be odd if nobody was home his little sister would be at school so she wasn't there his dad was probably at work he was writer for one of the cable networks but nothing that was over popular not that his writing was bad mostly the shows creators lacked interesting plots and his mom could be home either sleeping or in the family TV room watching the game show channel he didn't hear anything which was odd cause he could hear better than before he new this cause when he turned on his car radio it felt like his ears were vibrating cause it sounded so loud so he turned it way down to the lowest setting and could hear it like it was halfway up before whatever happened happened he was thinking about his changes again and all it did was kinda irritate him cause he'd done nothing in the weeks before like work out to get the muscle tone he had now his hearing was a mystery too he decided to check his room out and took the stairs 3 at a time he felt lighter he noticed also things were starting freak him out a little and he said to himself I'll just ask mom to make an appointment to see the doctor he didn't know what was going on he opened his door and his messy room greeted him books laying around everywhere he loved to read when he wasn't watching movies he thought about something and went over to the foot of his bed crouched down got a good grip and lifted and to his surprise he lifted his mattress easily like it weighed 5 lbs. when it probably weighed around 80 lbs he was very confused cause before whenever he rearranged his room he had to strain quite a bit just to flip it up on its side then push and turn it where he wanted it now he had it at chest height still flat like it was on the floor and before that wasn't something he would even think about doing it was just so lite now he just did it he lowered it back to the floor and tried to figure it out again something happened to him between leaving the library and getting to his Aunt and Uncles home last night but his mind was blank he couldn't remember even getting to their house he laid down and accidentally fell asleep cause no answers were coming
