Does anyone else get an increase in energy after the sun goes down especially with limited sleep the night before?

I find even on 3-5 hours of sleep, I drag through the day but at night I get wild amounts of energy. I’m not sure if this is just an insomnia symptom but it’s really annoying. My husband even notices and says things like “wow, you’re talking a lot tonight you sound very energized!” And then I’m like why?! I didn’t sleep a wink the night before I should be exhausted??
