"Do you really believe I'm making all this up?"

Rachel answered with caution. "I believe that you believe everything you've told me."

"So, I'm still delusional."

"You've got to admit, you've been having disturbing hallucinations for some time now. Some of the recent ones are classic religious delusions."

"But most not," I reminded her. "And I'm an atheist. Is that classic?"

"No, I concede that. But you've also refused to get a workup for your narcolepsy. Or epilepsy. Or even to get your blood sugar checked, for that matter."

I've been worked up by the foremost neurologist in the world. "That's being investigated at work."

"By Andrew Fielding? He wasn't an M.D., was he?"

I decided to go one step further. "I'm being treated by Ravi Nara."

Her mouth fell open. "Ravi Nara? As in the Nobel Prize for medicine?"

"That's him," I said with distaste.

"You work with Ravi Nara?"

"Yes. He's a prick. It was Nara who said Fielding died of a stroke."

Rachel appeared at a loss. "David, I just don't know what to say. Are you really working with these famous people?"

"Is that so hard to believe? I'm reasonably famous myself."

"Yes, but… not in the same way. What reason would those men have to work together? They're in totally different fields."

"Until two years ago they were."

"What does that mean?"

"Go back to your office, Rachel."

"I canceled my last patient so I could come here."

"Bill me for your lost time."

She reddened. "There's no need to insult me. Please tell me what's going on. I'm tired of hearing nothing but your hallucinations."

"Dreams."

"Whatever. They're not enough to work with."

"Not for your purpose. But you and I have different goals. We always have. You're trying to solve the riddle of David Tennant. I'm trying to solve the riddle of my dreams."
