You get to know your own personal signs - a feeling in your stomach, taste in your throat, tingling on the edge of your consciousness. The suburbs on the fringes of tonight's particular destination.

Can your body lie to you?

So what kind is it going to be? Onto the floor, easing yourself towards the place while slowly reducing the conscious input and allowing the helper apps to take over in a smooth transition.

Or find a co-conspirator willing to discuss ... anything. Anything to help release the slow torrent you can feel building up. Theorise, vocalise, empathise. Until the rhythms in your head and body synchronise with the DJ's choice and you can hold back no longer. With a smile and a quickly muttered "gotta dance", you burst onto the dancefloor. Not like a cork from a bottle, its energy spent in fractions of a second, but like a second stage rocket firing - discarding the mundane technology which brought you here, and set to glide for another few hours.
