Meaning of a dream

Has I fall asleep
My dreams start to rise
My hope grows
My pain flows away

I see a red rose
So tender, so beautiful
I can’t resist a touch
But I forget that
Roses have thorns
And I began to bleed

Why is something
So pretty be so painful
Something so small
Be something so big

Blood red rose
In my dreams
Next to you
What does this mean?
