There are not many businesses you could start that would allow you to make money in your absence because when you are absent from the business place, many employees and managers could take advantage of your absence and this could cause loss. So, the only option you have is to trust your manager or make such kind of business system that would not allow the managers or employees to take advantage. However, the only business I know where you could make money sleeping is cryptocurrency mining. It only requires you to manage the mining equipment the whole day or before you go to sleep. Your computers will be making money for you while you are asleep.
