Hey. At first this reminded me of the times when after a nightmare when your half asleep and half awake, tryin' to scream but nothing comes out. Tryin' to breathe, but all you want to do is scream. Trying to get help, and you know no one can hear you... I get that alot, and I know alot of other people who do too, so I hope that wasn't just random blabber for you lol...but anyway, that's what it first reminded me of. However, the more I read on, the more it just made me think of things like 'freedom of speech' and how, so many people seem to think they need to stay quiet because it won't help anything to shout. But then when (if) they realize they can do something, there's no holding back.
There's so many things I saw in this poem, and it really depends on your angle of thinking for what you take out of it. I really like that in poetry, when each individual reader can take what they want out of it. Very well done.
