Where is the line?

There is a line, what doesn't cared by anyone. They pulled this
line when they were born, amongst the two world, brightly put down
the footstone, in their opinion the worlds can never unite. They
have never been thought about how thin is that line. Sometimes it
costs just a flutter, and they are in the other world. They can be
mad here or there, if they preoccupied onto the wonder. Dizzy
feelings, phenomenas can be feel, or they can meet unbelievable and
enthralling beings. The light and the darkness is everywhere. They
can feel the pain, and hope it will be gone. But no, there's always
a little mark. In the soul.
As a matter of fact,the soul is the brace, because the soul doesn't
know lines, depth, and above all, impossibleness.
Hereby sometimes the line can slur.
You hear sounds -what others not.
You see something- what isn't there in fact.
You feel a flavour- what you can't.
You feel a smell-what certainly not.
Someone swept behind you- but noone's there.
They say its hallucination. Because they can't express it.
Could they ever express the two worlds? Not really...
