Sounds like you had one of those life-changing dreams. That's a good thing -- you learned something from one of your dreams. It is one of the functions of dreams. You aren't insane, you have a lingering atmosphere of the dream. I've had these, where the feeling of the dream lingers while you're awake. If you can learn how to control the atmospheres you feel, then you can get rid of it, or change a bad one to a good one.
