What is that feeling?

What is that feeling, when you believe in something?
How do you describe it?
Is it like when you have a vivid dream
and then you wake up believing it was real?
Or is it more durable like an actual experience?

How does it feel exactly?
Does it hurt or does it shine inside you,
giving you some kind of eternal bliss?

My deficit for belief is rooted in my veins,
directly pumping to my heart,
poisoning it with disbelief.

So I'm hoping someone can tell me...
how does it feel when one believes.
