I tried to fix the run-on myself. I added a few other sentences I would like you to check. Thank you very much for the help.
1) Sleep is imagined as a bath after heavy work, in which the body has a chance to relax and recover from injury.
2) Sleep is then compared to a little death, which comes at the end of each day.
3) "Will all great Neptune's ocean wash this blood Clean from my hand? No, this my hand will rather The multitudinous seas incarnadine, Making the green one red.” illustrates how no amount of water (of the ocean) could clean (wash away) Macbeth’s guilty conscience. Nothing can make his hands innocent. He will bring corruption to all he comes in contact with.
4) He imagines that all of the water from the ocean could not clean his hands of the burden of guilt that weighed so heavily on his tormented mind. He pictures Duncan’s blood staining the entire ocean red.
5) The blood on his hands is on the one hand symbolic of the evil crime he has (had) committed and on the other hand is a representative of Macbeth's guilt which cannot be escaped/cleared.
6) It is more likely that his hands turn red all the water of the ocean, than his hands are made cleaned by the water. (Can you help me here???)
1-5 sound OK.
6) It is more likely that his hands would turn all the water in the oceans red before they could be cleaned by the water.
