Dr Rahul Jandial says awake brain mapping can trigger childhood nightmares

What was said

"But when we tickle and map the brain, they'll say, "Oh, I remember this nightmare from when I was a kid." You can activate a recurrent nightmare in a patient by tickling the surface of their brain."

Dr Rahul Jandial says that during awake brain-mapping surgery, stimulation of the brain’s surface can prompt some patients to recall a recurring childhood nightmare. He argues this supports the idea that recurrent dreams reflect repeatable patterns of brain activity.
