You feel as if you were in one of those dreams where you try to move but you just can't do it. It's much the same feeling, but you're not dreaming. You are awake, although you seem to be miles away.
Since you're not asleep, you can see life passing around you. People here and there and they don't look like you, stuck and being unable to move or to do anything. They look alive, and you begin to realise they're infinitely different from you. You want to ask them why they can live whilst your life has suddenly stopped, but they can't hear you. They can't even see you.
You try to shout, but your voice doesn't get out of you. You try to cry, but your eyes have no tears. Only then do you notice how cold the world can be, but no sooner do you feel like that than a glimmer of hope appears.
Someone from that crowd looks at you, and you start being able to move again. Now you can breathe, you can yell... You're alive again, and now you realise that the only thing that you needed was someone to home in on you. You needed to feel that you were alive for somebody else.
