Wasted Energy?, Energy at a Major Concert Options

Be Well All..This question might be in the wrong area so I do apologize.. and if this question has been asked in the past..just blame it on the new guy! In a concert setting regardless of the rock band playing (or does the band make a difference?) With all those loyal fans screaming at the top of their lungs A Great Amount of Energy is being expelled..and with such a large crowd focusing that energy flow, who is the absorber? Or What..

i feed of the energy in concerts and partys. Its fun and gives a good boost of energy.
Although sometimes i just play with it. I saw tool live a while ago and i did not really feed directly of the energy.
I pushed out a lot of my own energy and then i mixed that with the rest, this way i could easily control the flow of the energy at the concert.
I then started spiralling it around and around, seeing how high density i could make it. Then i just let it go, out of respect for the fans and the band. Because i am a huge tool fan myself.

At other partys i absorb every excess energy floating around, but i do not suck on the people directly. I just take in the surplus of energy gathered in the air and suck it all in.
Its quite primal in nature, its kind of raw energy without a purpose anyway, if i didn't suck it in it would just drift away.
At times i have the feeling there are other "feeders" around, it feel like a tug of war then, each to suck in the most energy.
At the concert most of the energy is directed towards the band, out of the fans respect and enjoyment of their music. But at a normal party the energy is just from the excitement in the room, its not directed at the dj at all, since he is just playing music from other people and is not really recognized by the visitors. However the dj is in a good position if he was a psy vampire, overlooking the party.

I'm not really sure about all this though, it could be my imagination. But even if it is just mental mastrubation, just playing in my mind, its fun anyhow. (IMG:style_emoticons/default/laugh.gif)
