The optimal solution for me has been to combine both approaches. It’s very simple, and many early risers do this without even thinking about it, but it was a mental breakthrough for me nonetheless. The solution was to go to bed when I’m sleepy (and only when I’m sleepy) and get up with an alarm clock at a fixed time (7 days per week). So I always get up at the same time (in my case 5am), but I go to bed at different times every night.

“Yes, lucid dreaming exists,” said Dr. Rodney Radtke, the medical director of the Sleep Disorders Center at Duke University. “Yes, people certainly can, within their dream, realize ‘this is just a dream’ and continue to participate.”

“Do I believe that someone could potentially alter or interact with their dreams in such a way that they could change the dream? Yes,” he said. “Do I think that you could essentially design a dream — ‘Oh, I want to go to Honolulu and have this big hunk hit on me’? It’s a bit of a stretch. But I can’t say it can’t happen.”
