I have not read a lot of poem in my time but I have some knowledge about it.
The first thing I noticed was your title. I think you didn't need to put the '~ Dream Journal Challenge Poem~' because you can either put it in your short summary or your author's note.
Second, you should have used other punctuation marks besides the period. Unless I am mistaken. I think you forgot to use the question mark in your question (e.g Why don’t you listen to this rhyme.)
You also could have separated this sentence: But I do remember all the pain you caused me, yet you will never break this cast.. You would probably re-do the whole stanza again though.
Now for grammar mistakes, your forgot to put an apostrophe on: its you,. It should be it's instead of its. That should only be used when you're talking about an animal which you're not.
All in all, I don't really understand some of the lines but I think I got the gist of it. It's a very nice poem but I think you could have done it better.
