Why is my mind so insane?

In my dreams my mind tends to stretch reality and dreaming and I seem to lose which is which. You know that place between asleep and awake. Well, while I'm there I always dream I'm falling off a cliff or into a ditch. I'm still trying to figure out the meaning of it. One dream that frightened me was fairly short. It was just catastrophic. My teeth began to crack down the middle and fall out. I told my mother and she told me she had had a dream with her teeth falling out. Strange? The oddest of it all was this morning when I woke up. I had been up now for about 15 minutes, lying in bed and thinking about when to get out. I heard my father in the living room. All is quiet and I hear a laughing noise travel from outside my door to the living room. It remined me of one of those gremlins. I was pretty freaked out. Nothing like this has ever happened before. So I sit still for a minute with chills up my body. I finally get the nerve to get out of bed. I see nothing so I walk out into the living room and ask my father if he heard a weird noise or if the computer had made one. He said no, and no one else was up and no television was on either. My dog was outside so I'm basically down to no options. I think my mind is playing tricks on me. I know I can't be going crazy. But the laugh seemed so real. So scary. I still haven't figured it out... I doubt I ever will. And it was not a dream!

It didn't.
