covered in blood

I walk alone in the dark
The snow swiriling around me
The thoughts in my head
Are trying to overtake me
I cannot remember the past few hours
And the questions keep forming
All I remember is the man
Coming towards me
And my vision going red
I need a clue as to what happened
Something that can help me remember
But as I look at my hands
The memories come back
Because thay are covered
In blood
