speechless

What are the words for it?

The times when you sit down and see the world suddenly enveloped in sunlight; the hazy drifting air; the startled contrast of grass meeting the tarmac; the red-brown freckled tiling; glare of sun off the back of a metal chair; and yourself zoomed out into perspective, into the bird’s eye view from man’s eye vision…

People noises like ribbons looping by.
A tree waving in an unseen wind there…
a car slowed, achingly persuaded over a speed bump there…
everyone around you familiar, friendly strangers…
you turn your head, lift an arm, curl a finger, everything moves in a lazy lagoon…

A heartbeat, and you snap out as soon as you slip in.

What are the words?
