I think that dreams are basically our minds wandering around in a less controlled environment. Sometimes dreams can reflect something we've been worried over or thinking about. Sometimes our minds can find a tiny memory of someone we saw just one time and don't even consciously remember. Sometimes dreams are connected to our fantasies or our intuition. I believe they are a way for the mind to unwind or cool its engines in preparation for sleep, or they can be a way to express stress. I do think that our dreams can often tell us something about ourselves.
Weird if you don't know them.

I hope nothing. My dreams are usually weird.
