Dream of White UFOs

Today I dreamed that this guy offered me some infared goggles, he said I could use them to see UFOs. I declined. However I also dreamed that I was looking up into the sky and I could see little white flying saucers way way up high in the atmosphere. The were just swirling around up there and you had to look very very hard to even see them. I also some other things flying around a little lower, they looked like planes but they were in another dimension or they were invisible but I could see them.
