And next right here, our series this week, sleepless in America. Tonight, 23 million of us wonder if we're going to go to sleep or stay awake all night with insomnia. Well, what if there was a similar by way to drift off to sleep, and for free? ABC's linsey Davis shows us the new sleep whisperers who say, they can change millions of lives. Hey, guys. Today, I have a new video for you. Reporter: If just hearing her voice makes you suddenly have the strong desire to doze off, Ilse blansert won't be offended. In fact, it's the response she wants. She is a sleep whisperer, one of an exploding community on the internet known as autonomous sensory meridian responders, or asmr. They tap, brush, pour and mostly whisper, all to lull people to sleep. Makes really nice sounds. Reporter: Is it just a smoothing voice? Is it a calming voice? It has to do with the combination of sounds and voices. I'm not convinced that it works, it actually works. Reporter: Her videos have generated nearly 16 million clicks. And herps are among the thousands of asmr options. One of her followers is Emily Hansen, who says her videos have changed her life. I could not sleep and I was just thinking about so many different things going on in my life. Reporter: When Hansen saw her first asmr video, she found it hard to keep her eyes open. It was one of the most euphoric experiences I've ever felt. I didn't know what it was but I was hooked. My brain relaxes so much that I just fall asleep. I mean, I just conk out. Reporter: And that's with no pills, no side effects, no danger of addiction. It is quite believable to me that somebody says, this works better than a sleeping pill for me. Reporter: In fact, khan says that asmr videos could be a good solution to insomnia. It brings me comfort that I can't find in other things. Reporter: Millions of people now relying on the internet's equivalent of counting sheep. Linsey Davis, ABC news, New York.
