What could this dream have meant 4 years ago?

there are three popular theories about dream interpretation and meaning. 1) dreams have no meaning, and are in fact random flashing of neurons caused by mive amounts of brain activity that takes place during sleep. 2) dreams are caused by the brain making memories of your day, and as the memories are made, the parts of the brain effected by the memories are active, so you get flashes of your day and thoughts, which your brain tries to make sense of, and turn into a story. 3) the Freudian theory of the things in your dream containing a deeply hidden message from your subconscious mind. the original theory is that certain things will represent the same thing to everyone on earth. that is why i don't buy into it. i lean toward the second theory. that is why i don't believe your dream is saying much at all. the more you think about something, the more likely it pops into your head at night.
