last night I had a dream in which I was in a french hotel with my family and from the hotel I could see a chemical factory, a volcano that also launched rockets and a nuclear power station

then in the dream there was a massive lightning storm and the entire lot was blown up... firstly the chemical place went, then the volcano and lastly the nuclear plant... it all went kaboom... and thats it... however I don't understand this dream what so ever... any thoughts please
