Take a breath… better make it a big one

Ok, you’re mine now; I have your imagination, let us proceed…

• Hold onto that last breath. This is important.  Relax though, everything is completely fine.
• Open your eyes; it’s fairly dark, but you can see a dim circle of light some way in front of you.
• Look to your right and do please hang onto that last breath; about half a metre from your right elbow is a wall of rock. Now look to your left – ditto.
• Look up; there’s a rocky ceiling, also about half a metre above your head. Trust me though, everything is fine, but do please hang onto that final breath.
• Look down and keep holding that last breath; you’re sitting on white coral sand.

and then it gets very dark…

Oh, and by the way, I should probably have mentioned it earlier, but there is fifteen metres of water above your head, so if I were you, I’d carry on holding onto that last breath while we work out how to get you out of this self-inflicted predicament…
