Blind

defenseless: unprotected: lacking any form of protection and therefore vulnerable.
Or something completely different.
Something so intense that you can't see straight.
You're standing on train tracks-
Your feet feel the vibrations and slowly your whole body is engulfed.
You're powerless and exposed, yet you refuse to leave.

wanderlust: desire for traveling: a strong desire for traveling.
Or something completely different.
Something so strong that when you're in it,you don't even know you're trapped, the rusty steel is attractive and you're not sure why.
It is a desire for something: an intense longing for someone.
That is for whom your heart keeps beating.
An intriguing combination, because they also rob you of your breath.

fear: feeling of anxiety: an unpleasant feeling of anxiety or apprehension caused by the presence or anticipation of danger.
Or something completely different.
The tracks are laced intricately into the scenery.
Curves and sharp turns throw your awareness.
As the 200 ton vehicle approaches that is when your wanderlust turns into a poisonous parasite, fear leaves and defenselessness pairs with your rapid infection.
love: treacherous and so dangerous
