your punctuation flickers in and out like the power. you use the archaic form of putting caps at the beginning of each line. a good rule of thumb to see if a poem (of this type, as this test doesn't work on all styles) is to turn it into prose and then read it. so, this is what you have:
The wind crashes, the lightning strikes The lights flicker, the powers out Visions diffused, in the dark light One man's soul, cries and shouts.
all in all, it's a bit of a mess, wouldn't you agree? and i think you meant to write "power's".
