Massive mushroom cloud ---in dream last night; GLP effect?

In my dream i was in the place where i grew up,Sighetu Marmatiei , is located right on the border with Ukraine in northern Romania. From the hills in our orchard i can see Tisa river and Ukraine is just 3-4 miles away, and in my dream i was there looking north towards Ukraine, was overcast kind of dark close to sunset. I saw a huge dark blue mushroom cloud covering the entire horizon, expanding under the dark clouds then another one a little bit on the left ,west as i was facing north with lightning sparks at the base; Sorry,maybe i shouldn't post this chit, but honestly was frighting, vivid .
