Answer:
I think William Blake felt like he wanted to escape based on the poem. He wanted to leave the child labor industry because he couldn't take it anymore.
¨Could scarcely cry ¨Weep! weep! weep! weep!¨ So your chimneys I sweep, and in soot I sleep.
I believe he´s trying to say that he hates the conditions he´s in. Based on this line of the poem.
And so he was quiet, and that very night, As Tom was a-sleeping, he had such a sight!-- That thousands of sweepers, D, Joe, Ned, and Jack, Were all of them locked up in coffins of black.
I believe this is trying to say that the child laborers are punished by being locked up in coffins.
And by came an angel, who had a bright key, And he opened the coffins, and set them free;
The children were set free by an angel.
