Thunder can trigger a "sleep start." That is when you jerk awake. Your brain thinks the boom is a falling tree. Survival instinct.

Some people report "storm sickness." Headaches from pressure drops. You are not broken. You are just a human barometer.
There is also "lightning smell." It’s ozone. It smells like a photocopier in heaven. Very metallic. Very weird.
How to Prove It Happened
Check your weather app. Look for a lightning map. If you see a blob of red near your house, case closed.
Look at the ground. Did you see white sand? That is lightning hitting sand and making glass. Called fulgurite. Frozen lightning.
Or just ask a meteorologist. They love this stuff. They will talk your ear off about cumulonimbus clouds. Their passion is contagious.
