Opinions on a quote

"Dream, we must not shudder; For in despair our minds run for cover."

I intended it to explain how Life is like a dream with it's own rules, that to "shudder" is ultimately the result of our despair. This meaning to shudder in the sense of body movements representing terror towards an external source. The part about the mind simply means that our minds will "hide" from these sources by whatever means necessary,

I'm asking for opinions/critiques of it.
Thank you.
