Last night, as I tried to fall asleep, I was interrupted a number of times with weird dreams. I can't remember who or what the dreams were about, only that they were about friends or family, as if I was just an observer. I was disturbed enough by them that I kept waking up and trying again to fall asleep. I wish I knew why it kept happening. What do you think? Is it true that dreams are the mind's way of working out details that it couldn't process during wake time?
