Across the universe

hi!

I'm a finnish student girl and i'm asking meaning for a funny sentence from a song "papercup" performed by Heather Nova. So what does she mean by saying
" like nights in a papercup, when you wanted it to last"?

Thank you all!

I found the lyrics, in case anyone wants context:
Paper Cup

Wishful thinking I might be yours
Drifting on every step
I'm always drawn to the dark horse
Sweet sweet nothing's said

And every dream is just a dream, after all
And everything stands so still when you dance
Everything spins so fast
And the night's in a paper cup
When you want it to last

Wishful thinking you might be mine
Every shiver sends
One breath under the bridge of sighs
Bending where the river bends

And every dream is just a dream, after all
And everything stands so still when you dance
Everything spins so fast
And the night's in a paper cup
When you want it to last

And every dream is just a dream, after all
And everything stands so still when you dance
Everything spins so fast
And the night's in a paper cup
When you want it to last

And everything stands so still when you dance
Everything spins so fast
And the night's in a paper cup
And you want it to last

I'll leave the meaning up to those who think it meaningful....

Compared to some things I've read in the paper, this is meaningful. A paper cup is something temporary, something not expected to last, something with an ephemeral life. Tonight's pleasure might as well be in a paper cup, something that can't last. I suppose if it were in a glass tumbler or a crystal goblet it might last longer. At least the container would. SS

Remember John Lennon's lyric?

Words are flowing out like endless rain into a paper cup,
They slither while they pass, they slip away across the universe
Pools of sorrow, waves of joy are drifting through my open mind,
Possessing and caressing me.
Jai guru de va om
Nothing's gonna change my world,
Nothing's gonna change my world.

Images of broken light which dance before me like a million eyes,
That call me on and on across the universe,
Thoughts meander like a restless wind inside a letter box they
Tumble blindly as they make their way
Across the universe
Jai guru de va om
Nothing's gonna change my world,
Nothing's gonna change my world.

Sounds of laughter shades of earth are ringing
Through my open views inviting and inciting me
Limitless undying love which shines around me like a
Million suns, it calls me on and on
Across the universe
Jai guru de va om
Nothing's gonna change my world,
Nothing's gonna change my world

We miss John.

Yes, we do.

Maybe paper cup refers to its use as a "go cup."
