Chasing

"Sam, you've told me nothing! You have a dream about a girl, who loses her sister in a fight with a demon, and no we're going hunting...what?"

Sam spun the laptop in his brothers direction to show a picture of a human shaped demon, with read glowing eyes, a winged cape and red glowing eyes.

"That.." he pointed and his brother read the description beneath.

A wide variety of explanations have been proposed by authors who support the paranormal origin of Spring Heeled Jack. Due to the inherent nature of the phenomenon, such theories are speculative and bereft of any proof. The following are just a few:

A common hypothesis proposes Spring Heeled Jack as an extraterrestrial entity, somehow stranded on Earth. Supporters of this theory believe this would explain his non-human appearance and features, (e.g., retro-reflective red eyes, or phosphorous breath), his jumping ability (by suggesting that he may have been native of a planet with greater gravitational pull, like astronauts experienced on the Moon), strange behavior (which could have been altered through Solipsism Syndrome or as a result of breathing the gases present at the Earth's atmosphere), and his longevity.

A visitor from another dimension, who could have entered into this plane through a wormhole or dimensional gate.

A demon, accidentally or purposefully summoned into this world by practitioners of the occult or who made himself manifest simply to create spiritual turmoil.

The supporters of the paranormal explanations usually refer as proof of their claims that no human could have ever used a gadget to leap the way Spring Heeled Jack was said to, by pointing out that in the 20th century, the German Army experimented on the subject with disastrous effects. Allegedly, such experiments gave an estimated 85 rate of failure, with broken legs and ankles on the testers. They conclude that there was no possibility for an individual to succeed where an official warfare project failed, especially considering that the former had preceded it by many decades. It might be worth noting that there currently is a comparable device being marketed , but this gadget requires modern, state-of-the-art carbon fiber springs.

"Why, the sister's already dead...has been for three weeks according to the news reports, so why did you get me up at 5am to research?" Dean asked grouchily.

"Because it's not done yet, it wounded her three weeks ago, and those wounds have not healed, at all...and now she's chasing it!"

He remembered the second dream she'd invaded, he had seen in, the wound where she had struck her head scarring, to leave a single subtle strand of white hair, that she would never dye, she would keep as a memory, a kick every time she looked in the mirror, a constant nagging reminder that she was still alive and her twin, the one of them who had departed a little from their ancestral life as a hunter, ha got married and had children of her own, had rebelled, and that she, Lucia, the good little soldier had survived. Sam had felt that emotional turmoil and he had felt the physical pain as she had sat back in the car and disturbed the dressing on her back.

Sam knew this woman needed them and Dean, however much he complained, had learned better than to ignore his little brothers prophetic dreams.
