ear beating - The loud thumping in your ears when you're trying to sleep,

The loud thumping in your ears when you're trying to sleep, like your head is playing a beat drop from hell just to make you lose your mind.

I couldn't sleep because my head was making a beat drop. It was like a party in my skull.

I thought my neighbor was having a seizure. It was just my ear beat trying to ruin my night.

I counted my ear beat for an hour. Now I’m just tired and confused.
