This piece describes a mental state where a person's thinking is confined or limited in some way, either by external factors or their own internal processes. As illustrated, the man is confined not only physically but also mentally, unable to think outside of the box and thus trapped within his own limited perspective. Where it gets interesting is that every seconds he is trapped in there, he looses a part of himself, his body and mind is getting weaker. In most cases like this, people may not be able to get out by themselves, they need an external force.
