I had a wild dream about alien shapeshifters bombing Hobart, then posing as rental agents to assess the damage. They offered free hummus and wine to sterilize people, saying things like, "Drink plenty of warm alcohol! Heat it on a flame to keep it toasty!" while demonstrating storage on a lit gas stove. They called humans "the tired ones." I didn’t get why they pushed hot alcohol or cursed hummus, which I don’t like. One shapeshifter, a fake Asian woman, tried setting up invisibility shields around a crashed ship in a nearby yard. When I grew suspicious it gave me hummus and turned into a rasta man. Still skeptical, I got more hummus and it became a white man, cursed me silently and vanished.Their ships were grey-tan stone with carved glyphs, shaped like stretched pyramids with sharp ends. Four acute isosceles triangles (base half the sides’ length) formed the pointed end, while four equilateral triangles at the base curved into a smooth dome, only visible as separate parts post-crash. Each ship held five or fewer aliens, with thousands crashing globally, possibly due to outdated telemetry from a thicker atmosphere.Their bombs flashed red-orange, spewing grey smoke that knocked people out. Some seemed like weapon tests, not just crashes. Spotting a shapeshifter got you hummus or wine, induced sleepiness and the alien would transform and flee. The news called it a "street protest over austerity." They controlled perception, arousal and movement but not memories or choices. Their fake identities mimicked people’s memories, like one posing as my ex-stripper cousin, so I played along. I kept passing out around these shapeshifters never seeing their true forms. I’m narcoleptic in real life and for the first time in a dream. I woke up realizing my stripper cousin was a shapeshifter infiltrating the house.

(I used AI to shrink the length of my original post attempt but it didn't miss any details)

Anyway I assumed they have been here before when the atmosphere was thicker and that's why they miscalculated their landings.
