going through walls

One day there was a boy called Jeff he was in his house then when he went to bed then he had a dream that he was sleep walking. Then when he was sleep walking he imagined he went through a wall and when he did he saw a bunch of people some were trying ti get out but they couldn't. So he tried to get out so he helped,he was the only one that could get out of the wall so he got a sledgehammer and it didn't work but then. he could never brake the wall down.
