Topic PLN

The topic that I have been researching in my independent reading has been about aliens and UFO's. The main argument is whether aliens are real or not. I have read several articles on the computer about people having strange dreams and  getting parlyzed in those dreams. The question is was it a dream? People who say aliens don't exist are very closed minded in my opinion because to think we are the only life forms in the whole universe is just completely improbable. I would like to look more into my subject and find more arguments and dreams people have had to show how just maybe, we aren't the only life forms in the universe.
