who are you

Who are you?
Do you even exist?
Or are you just a perception,
a long dreamt image,
written permanently in mind,
like childhood in veterans.

You keep coming back to me,
like a bat in old house,
loyally and promptly,
shying away from light,
and gone in night,
leaving sleepless sleeps.

My legs are shaking,
eyes are burning,
like that of a fisherman,
who is fighting a hurricane,
and lost his boat,
and like a goat,
who is at edge of knife,
and struggling for life.
