I have to caveat this dream, with a new interest of mine - following volcanic activity. They are just awesome! I was just about to go shopping to Sainsbury's, no idea why, then there was there two volcanic eruptions. A smaller one emitting a lot of super-heated steam and a larger one exploding with a lot of tephra, (ash and dust). These to volcanic eruptions then merged into one culminating a huge major eruption. I still tried to go shopping in the midst of this but couldn't... for obvious reasons. The air was just thick with volcanic ash. There was a reddishness to the ash, (which could be iron oxides).
For some reason, I was enjoying the eruption... it didn't feel melancholy at all.
I have been following the activity at Taal, Fagradalsfjall, Grimsvotn, Katla, Etna, Campi Flegrei, Yellowstone, etc... I was wondering if the Lord was warning me about something that is going to happen.
"The Sun shall be turned to darkness and the moon to blood before the great and terrible day of the Lord". I suspect that could be referring to a huge volcanic eruption, ejecta being >1000km3 (VEI-8).
