Is that a sign?

I
How dare you to have a ground?
Even I close my eyes, I see you around.
You are a total stranger,
In my heart, I feel the danger.

II
You've shared those sad memories,
Likewise, I've shared you my history.
We're friends that's all I know,
why when I don't see you, time run slow?

III
If that a sign, can't believe it's true,
I know in your past you're not through.
You came into my life late,
And I don't know if I open my heart's gate.

IV
Can't sleep without your text,
Is that a sign?
Can't help but think of you,
Is that a sign?
I want to be with you
Is that a sign?
Do you feel the same way too?
Please give me a sign.
