The changeable person

What you mean,
When say that all have already seen?
When you say that is not so terrible to fight
With crowd of memoirs at night.
Recently you simply lay,
But it to leave all how before to try.
But now you became simply a phantom, vision,
Which unique purpose to execute the mission -
To take away my soul to itself,
And it needs to have time to be made to twelve.
Otherwise we will not meet more, and you even will
Forget to what at us was before.
