Dreams...What do they mean?

So the other morning, the alarm kept going off and I of course keep hitting the snooze button. I noticed that everytime I went back to sleep I had a different dream. Like a completely different dream. It was so interesting and made me want to sleep even more. Is this uncommon? Did my brain want to explore more of my inner thoughts. I probably had hit the snooze button like 15 times so I had about 15 different dreams.
