ICYMI Health features what we're reading this week.

This week, in honor of Halloween, our colleagues across HuffPost explored the science of our most commons fears and how we can overcome them.

We were also captivated by a frightening article about extreme sleepwalking, a sleep disorder that can result in the sleeper turning violent without any knowledge of his or her actions.

And on a disturbing note, we spent time with a story about the role of identity politics on the war on drugs in America, and how, as an increasing number of white middle-class families are torn apart by heroin, the conversation and punitive laws surrounding drug addiction are changing.

Read on and tell us in the comments: What did you read, listen to, watch and love this week?
