NEW YORK (AP) _ A 9-year-old boy dreaming that his parents were being murdered was seriously injured when he tried to escape from a third-story window in his sleep, police said.

Edward Amonte fractured his hip and spine and sustained a brain injury in the fall early Friday. He remained in stable but serious condition Saturday at Columbia Presbyterian Hospital in Manhattan.

The nightmare may have been prompted by medicine the boy took for a fever. His parents said he had a history of sleepwalking, according to police.
