Why does my brain decide 3 AM is the perfect time for existential dread?

I’ve been dealing with chronic insomnia for years, and it never gets easier to predict. Last night, I was finally drifting off when my brain suddenly decided to replay every awkward interaction I’ve had since 2012. It’s like a cruel internal cinema that only opens its doors when I’m exhausted. I’ve tried the meditation apps, the weighted blankets, and the absolute darkness, but nothing stops the racing thoughts once they start their midnight sprint. Is it just me, or does anyone else feel like their brain turns into an over-caffeinated debate team the moment their head hits the pillow? I’m genuinely curious if those of you with severe sleep disorders have found any mental tricks to actually 'shut off' the noise, or if we are all just doomed to negotiate with our subconscious until sunrise. How do you silence the monologue when the house is quiet and your body is ready to sleep, but your mind is clearly planning for a marathon?
