Tell Me What's Going On
In the beginning, Jake could still track the movements of his companions using his mental sense. But before long, they seemed to vanish, as if ripped from his mental grasp. Somewhere along the constricting neck of the funnel was a Faraday cage, aimed not at electric fields but spiritual energy, that scrambled his perceptions, disrupting and dispersing the mental energy he had forcefully engaged.

Yet, with the interference of the barrier and the introduction of this psychic Faraday cage, it became an intricate jigsaw puzzle.
