Ghosts are mere imaginations in your mind. You can make them live or inert, as you wish. Things happening naturally are highlighted by persons of weaker vision as supernatural activity. Whatever happens, it all happens in nature but not beyond nature. Our senses can’t sense what is not natural.

Well, I’m a psychic medium, so I have a lot of spiritual activity in my house, and I can tell you that none of that has or will ever happen in my house, because I won’t allow it. I’ve told my guides it’s a distinct no no. It’ll scare my kids.
But they can make themselves known by touching you (I’ve had my hair stroked). You’ll often notice a distinct icy cold spot in the room (or, in the case of the spirit kitties I’ve had on occassion, on a specific area of the body, such as the feet, which is where said kitties like to sit). The hair on the back of your neck will stand on end. You’ll get a distinct sense of being watched–when you’re completely alone. Ummmm, what else… sometimes you’ll notice things missing only to turn up in a completely different spot (you know darn well you put that right here, but suddenly it’s over there, and nobody touched it). You’ll often see shadows out the corner of your eyes, like someone just disappeared around a corner, but when you look, there’s no one there.
It’s all very subtle stuff and very easily dismissed as “my imagination” you know? It’s why there are so many doubters–I’ve been told by my spirit guides that it takes a good amount of energy for a spirit to manifest or to move things, and I get a sense as well that not alot of them even know how to do that stuff.

In the old days ghosts would hang out in old wind mills and other power generating devices.They would be active elsewhere during electrical storms.That’s why to this day.If you’re reading a ghost story or watching a movie.There’s a good chance thunder and lightening are in the background.

They take energy from all sorts of things other than electricity. They can draw energy from humans, animals, plants, fire, water & all earth elements.

A spirit will manifest from any electrical source dependent upon the amount of free electrons present, and the kind of strength or personality that person had in life. Sometimes near earth faults there is alot of magnetic energy which can stir up electrons, perfect condition for a spirit to appear or random strangeness to occur. A carpeted room, an improperly grounded house or even machinery and everyday appliances can cause manifestations.
So back in the day pre-electricity it just depended upon the amount of electrons stored up or conditions leading up to the contact. I think that’s why seances sometimes make positive contact – people generate energy fields and by making phsical contact with a wooden table and placing our feet on the ground, we are in fact making an electrical source for spirits to use to manifest.
Even home construction using several different kinds of materials can cause manifestation. Even in a log cabin with glass, leather, wood, a cast iron stove a pile rug, feathers(pillows) all these materials can store and release electrons when used.

they have been talked of since the beginning of time. Ancient Chinese accounts are written of. There are Egyptian accounts of visitations. The Greeks wrote of visitations from ghosts. They appear the same way as modern ghosts do, interacting with the living. By sight, sound, smell, rattling stuff. Electricity has nothing to do with their ability to appear, it just gave them new ways. Thats like saying how did people store their food, read, or use a sewing machine before there was electricity.http://www.en.wikipedia.org/wiki/ghost
