This is my first time actually doing this so you're going to have to forgive me if I'm a little off. But when I was listening my body temperature dropped significantly and I felt a cool, crisp sort of breeze blowing through my face. It wasn't unpleasant or too cold but it definitely felt like winter had arrived.
I could also sense something on my shoulders. Like a backpack or it could've been symbolic of carrying some kind of weight or burden around with me. Something on my back. It wasn't too heavy so as to be uncomfortable but I felt the distinct impression of wearing something on my back and on my shoulders.
Perhaps you do a lot of walking? A student that might wear a backpack around campus? I'm not sure that could be entirely off. Like I said the weight could be completely symbolic and there is rather some kind of burden or pressure that you feel around your shoulders and it's something you bare to the best of your ability.
I also could sense all throughout the song a flittering sensation much like if you were to put a firefly inside of a mason jar with just enough of a filter where it could still breathe. But it would flitter back and forth against the glass thinking it could escape but something was keeping it from breaking free. It was a frantic sort of feeling, a restlessness, a longing that was deep to the bone.
There's an overpowering sensation of feeling alone and misunderstood. There might be a small circle of people who understand but all in all it's like being a complete and utter ghost walking around in the dark. But this yearning, this desire to be seen, to be heard, to be understood; tinged with hope, knowing that there are those who actually truly exist out there who DO know you and DO understand you but they are far away and you long for that companionship and that closeness and intimacy of a true friend who knows and hears you.
Someone to help you carry that weight when it becomes a bit too much.
Again I could be way off but thanks for letting me try!
