Fire on the moors

I am on an open moorland - high up, vast.

It is on fire and I am running, running, running.

I fell myself running but also see myself from above, I see an endless sweeping line of flames traveling at great speed across the moor, seen from this distance I realise it travels faster than I can surely run.

Back in my body I see a squat concrete building ahead - "perhaps I will be safe in there?". I run towards it, it's walls are thick like a war bunker, but even as I head into it, I know that the flames will consume all in the end - even this.
