“Imagine waking up in the middle of the night, unable to move and being haunted by your worst nightmares? It’s what happens to those who suffer from sleep paralysis, like photographer Nicolas Bruno, known on Flickr as thewickedend. Nicolas endured these traumatic hallucinations for years. But over time, he learned that photography helped to control them.”

You can see Nicolas' photography through his account, thewickedend. Check out the original Flickr blog post for the whole story.
