Is there something wrong with me..?

There's nothing wrong with you, really! The same thing happens to me all the time. It's just a part of your brain that you can access subconciously that you aren't aware of when you're awake. Humans only use a tiny percentage of their total brain, you know. There's so much mental capacity, no one knows the whole of human ability yet. We still have some evolving to do before we figure out how to control it a bit better. So, don't worry. You're good.
