Energy

In a pharmaceutically induced state, I was able to draw enough neuronic power to craft a theory in regards to ghosts. We know that ghosts draw power from the atmosphere, from batteries, and from other electronic power sources. I propose they also draw power from humans. This would explain why people often feel uneasy and dizzy. Perhaps their subconscious mind is aware of the power drain and this is what triggers a fear response before there is any conscious reason for them to be afraid. The hair stands up on the back of their neck and their skin crawls with goose-flesh. All of this could be a result of the dead stealing power from the living.
