Hollywood is the blame for that notion. Majority of spirits just want to be noticed and paid attention to. Imagine this for a quick second. You were angry, bitter and torn on a twisted love that ended your fate. Intruders came into your home, you became bewildered and outraged – what do you think you would do as a person? You may throw things, you may knock or bang on walls, you may shout profanity at the intruders. However, could you have enough energy to actually grab one of the intruders and throw them down the flight of stairs? No, I hardly doubt it!
Spirits need energy to manifest, they need some sort of power to pick up something. Think of the old RPG games, if you’ve played some – there’s a bar that say’s energy and each move takes energy. Now, picking up something like an intruder would have to take tremendous amount of energy. You can think of this way, imagine you’re going to work out for the first time and you expect to life 200 pounds. Will you be able to do it? Say if you’re a skinny person and never worked out before – then probably not! Not saying that the spirits would have to work out by lifting people and what not. I’m just addressing that it could take a lot of energy for a spirit to even pick up the lightest object.
So where do ghosts get their energy from? They absorb energy from various of sources such as paranormal equipment, anything that’s running on artificial and natural current. By natural current, I mean ion’s from the environment such as the positive and negative ion’s in the air.
More energy they absorb, the more effectively they’ll be able to manifest. You can think of it as a video game’s “Power Up”. More “Power Up” the ghost absorbs the more powerful they will become. This energy will disperse eventually and they would have to receive energy elsewhere.
There’s been countless of investigations where no paranormal team has ever been hurt by a spirit, not even a malevolent one. If you were deceased, would your purpose be to harm another individual or would it try to get attention? You decide on that one.
