I think you mentioned on the old board that you were going to start taking melatonin to help you sleep, Courtney? Melatonin can affect dreaming for some people-- I personally went from having a memorable dream once every few months to having very vivid dreams as often as a couple of times a week, and my dosage is pretty small. Lucid dreaming (ie, dreaming when you're still half-awake) can be a side affect of a heavy dose of melatonin. Also:
aliens
If someone believes that aliens are "among us" or are visiting earth, they're almost certainly wrong (and supposed abduction experiences are probably also lucid dreams), but given that there are probably hundreds of billions of planets in our galaxy alone, it seems unlikely that there is nowhere else in the entire universe where at least single-cell organisms live or have lived.
dark matter
There's a brand of pseudo-sciencey new ager who takes things like dark matter and quantum physics in a really weird direction, but as I understand it, there is some scientific evidence for dark matter. The dark matter hypothesis arose due to discrepancies between the apparent gravity of galaxies and the amount of mass in the galaxy that could be calculated based on the kinds of matter we can see-- in short, in order for a galaxy to have the kind of gravity we observe, there must be some additional source of mass in addition to the stuff we know about. Scientists began to suspect that the missing mass must be the result of some other form of matter besides conventional matter. Astrophysicists tend to suspect that this unconventional matter is made up of a different kind of particle than the matter we know. That particle hasn't been discovered, but by studying the movement of galaxies, scientists are pretty confident that there is "missing mass" unaccounted for by conventional matter and dark matter is at the moment the top explanation for it. (I'm totally not a science person, so Whitney, Jeremy, and Sami could probably find some errors here)
I don't really know about multiverse theory, but I think it's another one where New Agers and scientists are talking about different things, and the former are just trying to piggyback off the latter to better sell their snake oil
