My wife loves to tell me about her dreams. It is a daily occurrence to hear her tell about all the crazy things that happened to her while she slept the night away.  For the betterment of our marriage, I listen politely and nod every once in awhile.  I don't really dream much myself, or at least I don't remember them if I do. Occasionally, I will wake up mid thought and remember something, so I am not immune to weirdness of it all.  

The thing that gets me is that even if a dream seems real to the person that is dreaming it, as soon as that person tries to relate it to another person, it is just some thought they had that they are now telling aloud. Let me try and explain.... if you were just sitting next to someone at a dinner table and they said, "Wouldn't it be crazy if I was driving a car, and then suddenly it was 20 years ago and I was in my high school after hours, but, I am the age I am now and my boss is there and I just can't get my test done in time, oh yeah, and I am in my underwear" you would tell them to be quiet and maybe seek professional help. The idea that someone dreams something like this only changes the importance to the dreamer, not the listener.

My point, before going off on a dream tangent, just realize, it is just a thought in your head that no one else thought was real, except you. 

(Let the algorithm try and figure this one out.)
