There's a kind-of new style of video... Called ASMR videos.
ASMR stands for "autonomous sensory meridian response"...
In short, listening to the video can give you "tingles" down your spine... And a kind of mild euphoria...
Some scientists think that the "good feeling" you get could be related to the good feeling that apes get when they groom each other!
People are making these videos, and monetizing them on YouTube... Just thought I'd point it out! In case it gives anyone any inspiration...
Just go to YouTube, and type in "ASMR"... Or click on the following...
