Who I am?

The one o lurkes in your dreams
The one who stays in the mist
Like the wind I walk
But I can stay without a word
Some persons say that im unique
Others say that im an evil angel
Well im just yours
The person who have more walls in is mind
Who sees trough the eyes
Without my shine in the eyes...
Dangerous I can be
Consuming everything in my way
Yes im capable of break down everything
