DR (BGT):

Insomniacs sta mentally “on” at night because the brain’s background thought generator keeps running in sequential, problem-solving mode when it should switch to diffuse, non-linear rest mode.

Why it happens (micro-version):

• Daytime = useful linear thinking

• Nighttime (for insomniacs) = same engine, no brakes

• Low sensory input + darkness → thoughts TL;DR (BGT):

Insomniacs stay mentally “on” at night because the brain’s background thought generator keeps running in sequential, problem-solving mode when it should switch to diffuse, non-linear rest mode.

Why it happens (micro-version):

• Daytime = useful linear thinking
• Nighttime (for insomniacs) = same engine, no brakes
• Low sensory input + darkness → thoughts loop, chain, and self-trigger
• Arousal systems stay active; shutdown signals don’t fully engage

In short:

👉 The mind keeps narrating when it should be dissolving.

If you want, I can compress this even further into a one-sentence neuroscience version—or flip it into a practical “how to interrupt the loop” angle.
