Erases actual memory

A cloud,
Big, black and bewildering.
It conceals my thoughts,
Erases actual memory.

A sheet,
White as snow,
Yet still clears my mind,
Erases actual memory.

Tears,
Salt, sliding against my face,
Ceases thinking,
Erases actual memory.

Yet the most powerful..
Blood,
Red, metallic,
The pain of the cut erases all memories.

I haven't written a poem in quite a long time.
I know it's not very good at all,
But Carlos wanted to be typed on.
