Evil Elves

I was watching a couple stand on the beach and kiss.  In the distance I saw a tidal wave forming. I tried to warn them.  I couldn't get there fast enough or yell loud enough.  I turned to run back up the jetty as they were swept away.  I realized that I was very short, like a hobbit.  At the top of the jetty it connected to a boardwalk and a house I had not seen before.  Trying to escape the water I met a man and woman who I had met at a trade fair before and who I did not like or trust.  I climbed up to the house and met a dark elf who was also the father of the man I had just met while escaping the tidal wave. Although the house was modern, I was wearing more period clothing and the dark elves all had complex costumes.  I already knew something was very wrong but i fainted and woke up later.  I realized that the dark elves were using medical technology to make beautiful slaves. Strange modifications were made to the people to make them slimmer and also not able to eat.  One lady had a modification in her mouth that made foods taste bad. Some of the humans were airline attendants. Which I knew because sometimes the humans would be sent back for upgrades and I could see their uniforms.  It was disgusting and horrifying and I spent a lot of the dream trying not to look at things or here what was going on. The man I met earlier was actually made of some of the dna of the first dark elf I met.  The elves had to keep kidnapping people to get more genes to work with. From the porch I could see them fixing the scene on the beach which was really a trap they created to flood on cue to kidnap more humans. A lot of the experiments they did on people didn't work and they caused a lot of pain or made monsters.  One man was able to change his skin and hair color to make himself camouflage and the elves tormented him by throwing him around so that he had to change over and over. At one point they threw him outside and he looked so much like a dark elf with strange magic that as he changed to suit the grass and trees a light elf spotted him and shot him thinking he was a dark elf or just to put the man out of his misery.
