Вообще, to run high это когда эмоции захлёстывают/зашкаливают.

EMOTIONS run high, people don't. And this expression doesn't mean to be on drugs.

It can mean I'M RUNNING A HIGH FEVER, but that's all I can imagine without any further context.

>>EMOTIONS run high, people don't.
That's what I was thinking.

You were right!

If someone says “I’m running high” they either mean that they have a fever, or figuratively, they’re “overheated” with passion or lust. Sometimes we use this false “I” when we refer to something in close proximity like a car; you’ll hear people say “I pulled into a gas station” when they mean that they pulled THEIR CAR into a gas station. Similarly, sometimes you hear people say they’re running high when they mean their TEMPERATURE/LIBIDO is high.

When you’re on drugs, you say I’M HIGH (no “running” involved)

That's interesting! Thank you. 🙏👍

Я весь горю!

Yes!

In a sense, this means the same as “I’m burning up” (=with fever or passion)

Я весь горю (=у меня жар/я сгораю от страсти).
