All of our talk about dreams got me thinking about a subject no one really ever mentioned in class: deja vu. I experience the phenomenon frequently and it is suprisingly accurate. I often have the type of dream that is difficult to separate from reality while I am dreaming. I do all the things I normally do during a day and then wake up. However, after a few days the things that happened in my dream happen in real life, exactly how they happened in my dream. It is crazy. I thought about it and I came to the conclusion that deja vu is one of the ways we can tell we are not living in a "dream world". We can tell that deja vu experiences are real situations about which we have some previous knowledge, but what purpose do they serve. Is it possible to compare them to some sort of amateur prophecies or are they simply a phenomenon we have no way to explain? What do you think, how should we deal with the experiences of deja vu?
