This is serious, we had one prophet here, who said the same, already 50 years ago. People in this region had passed it on, into our time.
He said he got this message for us from God: "Three and a half days of darkness. Stay inside the house, lock your doors and windows, do not let anybody in, do not open the door!"

And "Have some canned food, all other food rottens.
Water will be undrinkable, so bury some canisters of water in the earth, this will keep your water clean.

All those who are outside will die.
This is God's cleaning up".

Thank you for posting your dream.

Best wishes to all of God's children here.
