Necessary for what.

Once you saved me from myself, the time i almost drowned,
no one knows of what i thought, the thought that threw me down,
i got so scared of a truth i found, though of it i never speak,
what had happened in my mind, made me mentally weak,
what happened to my body, that i will never know,
but what happened underwater, that fear will always show,
i saw a light, you'll see it to,
believe me, or just don't,
just know, i know i saw it,
who spoke next, i won't know,
but never shall be buried what they said, never will i forget a word,
they said, "it's not your time to go yet", and i know it sounds absurd,
but then i drifted to the time, where my friends were staring down,
each and everyone, adorned with a frown,
i still forget what happened, in those moments after the next,
but while i was underwater, what i saw needed no specs,
never will i know, what i was needed for,
but after this i've touched some lives,
of this i am sure.
