What does this dream mean?

Honestly, I've always believed in the theory that dreams are a result of your brain firing off excess energy as it deposits into your long-term memory. It's usually just random thoughts that are in your mind, but your brain is designed to "make sense" of information gathered, which is why dreams always tend to be so random and sometimes flat-out weird. It's a result of the brain trying to make some sort of sense out of the random thoughts that are there. Think of it as a way of your brain discarding, or setting aside thoughts. This is believed to be why people always tend to never remember dreams from about a minute after they wake up. The thoughts are only in you short term memory and are discarded as scrap, because your brain doesn't see any logical reason to have them. If it were me, i would see it as another dream, think nothing of it, and move along.
