What do these things symbolize in a dream?
-a cloud with fire
-smoke in a house
-a burning building
-the sky changing from light to dark in a matter of minutes
all these pertain to a certain dream
It really depends on
1) who is doing the dreaming
2) what it means to them
3) actions involved around those objects.
The last one, sky changing from light to dark in a matter of minutes would be like a real weather change-- which might represent a current change that's frightening to the dreamer. (Or maybe something else!)
An eclipse-- well to me, an eclipse MIGHT mean that something (whatever else I'm dreaming of) is blocking out the light of the sun (or Son.) It might mean something else to you.
A cloud with fire... I dreamed recently (last 6 months) of burning hail. It was something that represented a threat to me in the dream, but ended up not having much of a translation into my waking life.
A cloud with fire might represent guidance from the Holy Spirit, if it's in the form of a pillar (think of Exodus).
Or it might represents thoughts/beliefs about the future. (Everyone speculates-- it doesn't mean that the dream is necessarily a message about the end of the world.)
Smoke in a house is pretty vague. If it's caused by a smoker, it's an indicator that someone's boundaries (typically spiritual) are being "polluted."
It could also be an indicator that there's a problem ("where there's smoke, there's fire." Sometimes our subconscious will use wordplay.)
The burning building-- it depends on what type of building. If it's a church, it could be about intolerance, if it's a school-- it could be wishful thinking (it's the end of the year and our subconscious isn't usually very well behaved,) if it's your house, it may indicate that the dreamer feels he/she is losing everything around them.
I know these are vague-- sorry, but it's a jumping off point. Please don't forget to pray for clarity first. If you'd like some more help, please feel free to contact me.
