I had a dream like this 3 years ago, i was in my back garden then i saw a very bright flash (it was daytime in my dream) then i felt searing heat and all went black. Interestingly My house looked different when i had the dream, i had an extension and a conservatory. Because of this i put it down to just a silly dream, but know my house does indeed look like the house i dreamt of! Scary eh!
Hope it doesnt come true, what do you guys think of this?

sounds like a nuclear explosion.!!!

agree, does sound a bit like a nuke..
maybe a very powerful dirty bomb or something?
or maybe a preminition!
