A Washington man popped half an Ambien after surgery and woke up to a nightmare.

The 75-year-old's dream that he was in a plane crash turned into hallucinations that were so vivid, he dialed 911 to report an accident.

He told dispatchers that the small cargo aircraft in which he was traveling with three other people from his home city of Renton to Oregon had landed in a field with trees and that he was "pinned in," reports SFGate.

The others were unconscious and he couldn't see out of the window, he added.

In reality, he was having hallucinations at home after taking the sedative.

"He was very calm during the call, but sounded scared ," 911 dispatcher Becky McCracken told KOMO News. "It sounds real. And I've listened to it a couple of times. I would never know it wasn't real."
