Dreams.

If I don't have work, I manage to fulfill my obligations to my loved one and get 100% of the sleep I need. I started practicing "Out-of-Body Experience" (OBE) on the advice of a friend, and you know, I didn't have any particular sleep problems because the practice is done after waking up. That is, you wake up and after some time you need to catch the "Phase"... It's hard to explain this to someone who doesn't know much about it; I haven't achieved much myself, but I know for sure that it doesn't have much of an impact on sleep itself.
