Tibetan songs, sung by a woman, is prefixed with a horse barking, and there seems to be a line in the lyrics right in front of my eyes. What's that song?

Things of the past

The lyrics are as follows:

There is a cloud floating in the sky.

It is leisurely in front of my eyes.

Although it is close, I can't grasp its whereabouts.

Past events are like clouds.

Watch him walk away slowly.

Never think about me.

I hope one day.

Clouds turned into raindrops.

Fall to my lonely side again

I hope one day.

You are like raindrops, too

Hope to catch my heart.

(Music)

There is a cloud floating in the sky.

It is leisurely in front of my eyes.

Although it is close, I can't grasp its whereabouts.

You are like a floating cloud.

Although reflected in my heart

But you don't want me.

Maybe one day.

Clouds turned into raindrops.

Fall to my lonely side again

Maybe one day.

You are like raindrops, too

Hope to catch my heart.

(Music)

Maybe one day.

Clouds turned into raindrops.

Fall to my lonely side again

Maybe one day.

You are like raindrops, too

Hope to catch my heart.

Maybe one day.

Clouds turned into raindrops.

Fall to my lonely side again

Maybe one day.

You are like raindrops, too
