I can fall asleep and wake up whenever I want, but I want to shift my biological clock so I can sleep and wake up at a specific time. If I close my eyes, my mind stays wide awake for hours. Do you think I should stay awake until my target bedtime?

Thank you to everyone for their thoughtful comments and trying to help. I started a scary jinn story, closed my eyes, and listened to it until the alarm went off. Today I slept for 6 hours; I fell asleep at 12:09 AM and woke up at 6:10 AM 💫
