Of course, any electrical activity produces a little electromagnetism, and I guess that is kinda what pervades the surrounds beyond us...it just comes down to how far does it reach?
Like the dial on a radio, tuning into to something gets a specific intercourse between transmitter and receiver...be a little off station and it's all noise; be right on the button and it's clarity that only the radio lets out to our wonderful ears and brain and elicits activity that makes us possibly react in some way.
Some folk cannot be around even the slightest bit of electromagnetism because it makes them feel ill. Others somewhat thrive on the stuff...if it is the right kind of stuff mind you. So...how about you play with what affects you...let yourself try to reach out to what that transmission is for as long as the moment lasts...then go have a beer and really taste the atmosphere in your immediate surrounds. I'm sure someone will pick up on how you are feeling and have no real idea why they want to strike up a conversation.
