The Invisible Me

There’s a specific spot in Hyde Park that you can stand, sit, or lie down in, and no one can see or hear you. I’m no sci-fi geek, but I reckon it has to be some sort of phenomena.
Here it is: you become completely invisible. Seriously.

You’ll know you’ve found it when your ears become heavy with the lack of any sound.
Sit there and the grass doesn’t even bend under your bum.
Stand there, and any wind blowing only skirts its edges (watch the breeze swirl around you as if you’re standing in the eye of a tornado).
If the sun is screaming at you, it never burns your skin.
No one can see you, judge you, or mock you.
It’s so cool!
