Flight And Return

First a blinding light. Later, in swirls of hot wind,
closets, chairs, lamps, the same ceiling flew
out of gaping windows into cobalt patches of sky.
They knelt and dug , thrust into the floor,
as if planting new tree in the room. 
They climbed up showery foliage, looked down
over the bed, slowly descended, entered
their own bodies again, hands clasped.

Paula Grenside's Questions:

Though a tad surrealistic, is it clear what's happening?

All suggestions will be appreciated.

Thank you.
