I had a dream where aliens had invaded the Earth. However, many of them were in malfunctioning vehicles... I think the implication was that their main ship had blown up, and all of the debris/escape pods just happened to land on Earth.
The aliens which were trapped were able to send out these psychic screams which would either make people insane, or basically just kill them outright.
Anyway, for whatever reason I was visiting Aaron and we were driving around someplace that was mountainous & cold. We were in his truck, and the radio wasn't working. But all of the sudden, it started to pick something up - whistling, like old style radio tubes would do under interference. Aaron was like "must be one nearby." and started to turn the truck around.
I said something about the radio, and he turned the dial just slightly and we suddenly heard an old style radio program. It sounded like science fiction from the 20s. And I was like "DUDE. This is ours. They're trying to communicate!"
So, we keep driving until we find the crashed alien ship, and it looks different from all of the other crap around it (and it's only slightly larger than the truck). We end up getting out of the truck and knocking some mud off of the ship, which allows it to free itself from the rest of the caked on mud and open the front door.
Aaron disappears somewhere, and I'm left standing in front of the ship when a caterpillar about the size of a mastiff comes out, looks at me, and then goes invisible.
