chasing dreams

I've always wondered why we dream what we dream and why sometimes we can remember it so vividly and why sometimes it comes true. I know there's all those books out there on interpreting dreams and if someone's chasing you, it supposedly means that you have anxiety in real life or if your falling in your dream, maybe your overwhelmed. I don't know if I actually believe all of these interpretations but I'm sure if you dig deep enough and look at every detail, dreams probably do actually symbolize feelings and actions in your waking life in some way. I think it's cool how the whole subconscious works and would love to study about this kind of stuff for fun. I rarely ever dream (well I don't remember them) I used to when I was little, but I love remembering my dream from the night before especially if it's a cool one! Here's a video of a dog running as he's dreaming. It's really funny! I'm pretty sure I've actually made movements or laughed if I was moving or laughing in my dreams! The poor dog ends up running into the wall though! take a look!
