I seem to be losing my mind.

I hear faint screams,
In the middle of the night,
They sound like my mother's,
Everyone says I am imagining it,
I seem to be losing my mind.

I see bruises, marks and scars,
On the face of my mother,
Dad says it's because she fell down the stairs,
Mother must be very clumsy,
Or I must be losing my mind.

I was supposed to have a sister,
But we lost her,
T'was fate, tells grandmother,
And no it wasn't she, who pushed mother,
I am just losing my mind.

I don't know,
I died a year ago,
I said things I shouldn't,
You see, I lost my mind after all.
