A friend once told me that our dreams are sort of premonitions to reality. We don't exactly remember the dream but it feels like it's already been experienced by our minds, and our minds tell us it's a feeling of deja vu; a sensation of vague familiarity. But why are there dreams that we do remember? Notice how those that we remember tend to be strange, unreal, and well, dreamy? I'm not an expert on dreams or whatever, but here's my take: we remember them because they simply are weird enough to happen in the real world; it stands out like a green apple among red ones! (American Idol 10's Brett reference. Haha.)
I think the subconscious dictates most of what our Mr. Sandman brings into our sleep. In the same way, bothersome thoughts and other worries do the same. So do the entire spectrum of feelings we experience each day, especially those that surface easily. Here's a conversation I had with my best buddy last night (well it was mostly me talking hahaha):
