I read a short novel about a technology that allowed you to have a VR like experience while dreaming. Of course, there was all the fun/perverted stuff you can think of but also it was immediately put to use as a corporate tool. Over a few years, more and more white collar jobs shifted to night shifts where you worked via dream VR. Then people were available during the day to do whatever, watch their kids, pursue hobbies, etc. In many ways- it was a very promising future.
