A triangle shape

Cauliflower Spaceship I am far away in space and in the far future. I am on a massive spaceship that was damaged from the inside, by a battle I think, I cannot recall. I am explaining to the crew that a chemical reaction near the engines created oxygen that was leaking to the fuel line, making us go way faster than we should. We were way off course, doomed to be lost in space as our ship was damaged. Suddenly our ship is destroyed. We have spacesuits on and float through space uncontrollably. I see an alien ship, it looks like a cauliflower. The front of it splits into 6 triangular pieces that open up to reveal a massive swirling portal inside the ship. We fall straight into the portal and find ourselves falling to an alien planet. Somehow we land safely. We are in an alien city that looks to be very advanced technologically. On the side of the road there is a booth that gives you a shower and new clothes instantly. I try it out and in a flash, my skin is dripping wet and I have a brand new suit on that is still warm like it was just ironed out. There is another smaller machine that creates coffee from some sort of recycling. It looks bad and smells like poop, which makes throw up before I even taste it. Dream ends. Memory-erasing hostile aliens I am with army friends next to a big lake that is unfamiliar. This location does not look like Finland. There is a mountain range behind us that the other soldiers turned to sand with some bizarre weapon. Then the dream gets confusing, because we encounter aliens that eat memories. I can only recall quick moments of action. We were driving in jeeps, most likely leaving the lake. Another moment there is a towering alien with no facial features, like a silhouette, standing in front of us. We start firing at it, but my memory cuts there. I recall the alien firing a green plasma orb. Suddenly I am standing on the road leading to my childhood home. The gaps in my memory terrify me. The aliens are using my worst fear against me. The streets are empty. I run to the house and turn on the TV. The news make no mention of the aliens. No one else can remember them, even though they could be everywhere. My brother is in the house and sees my worried look, asking what is going on. The fear wakes me up and persists even while awake. Takes a moment for me to realize that it is safe now.
