First I was at a dinner at my grandparents' house and for some reason I couldn't use one of the two upstairs bathrooms so I asked if I could use the downstairs one. It was kind of my grandpa's special man cave sort of thing and while he hesitated my grandma said I could right away. There was a little elevator that went down there that was closer to the size of a dumb-waiter-shoot and at that I decided I was now too big to go down it and that it might not be able to hold my weight. So the other way was a series of ramps. It was dark and night and from the ramp I was able to jump over to the metal cage that the elevator would have traveled down so I could climb down it like in the past. I remember my grandpa letting me do that (not in real life but in the dream memory) and he'd ask me to look for rust and damage. I did find a little bit but nothing really to worry about. Right at the bottom though I was outside and right away I could see someone scouting around and they saw me and lifted up their gun. I jumped into the light of a spotlight and raised my hands but they started waving at me frantically. It was then that an alien jumped out of the darkness onto their back and started eating them.
There was a bit of craziness that I don't remember quite so well but the next thing I remember I'm a part of this group of humans which is being guided by a special group of different kinds of aliens protected from this other alien which is trying to do bad things. The group of aliens is actually the intergalactic embassy of peace or something like that. And they have super advanced technology and such but the reason why they haven't included humans is because of all the races in the universe humans are the only non peaceful race. Anyway, the drama stems from the bad alien going to Earth and causing a bit of a problem that caused a bunch of damage and elicited the response from the intergalactic protectors. Due to the interaction the protectors accidentally bring a small group of humans to their main location. We are rounded up and brought to a holding location where one of the two main police ate an almond which made him really mad for some reason. He started lighting things on fire with his mind but none of the aliens seemed to be too terribly concerned.
Later, the bad alien trapped us all in a maze of triplines and mines but they all turned out to be duds. As it happens all his attacks were a build up to show that humans were actually a bad race that something should be done about. The reason why he tricked the intergalactic peace cops and us group of humans into the mines was to show that he wasn't actually being violent but just trying to prove a point. So once the question was put to a vote it was found that Earth should be destroyed, but that wasn't what he wanted at all because he really liked Australian things. So the decision made him really, really raging mad but that's when I woke up.
