The Oneironaut's Odyssey

Dream - Sky Beam
It's a post apocalyptic dream set in a scifi futuristic setting. I remember a part where I have a vision, a scene where I can see Earth from space and a huge beam of energy erupts from the Earth. It's a premonition about the end of the world which will occur in a few days. There was some kind of war against aliens which is why it's post-apocalyptic.
I'm in a place that resembles my parents house, there's a bunch of survivors here and they're grouped together having some kind of discussion about how to live from now on. I walk up on top of a huge boulder and address the crowd, knowing that they won't believe me if I tell them we have to leave Earth. "I know you won't understand now, but in a few days time it will all be cleared' (I said something like that in a very heavy tone, it felt super intense). I also spotted in the distance a large beam of a different colour shooting into the sky, I knew it wasn't the same as the one in my premonition.
There's a crashed old spaceship from the war with the aliens that we can escape on, but we need to work together to rebuild it.

Dream - Force field
I only remember a little about this dream.. It was a similar setting except by an arid cliff wall with the sun beating down on me and a group of people. There was a force field protecting our locale, I had to throw some kind of force field grenade outside it or something, can't really remember this part.
