Could this be derealization?

http://en.wikipedia.org/wiki/Derealization

The seems to be related to dissociation.

I had periods in my life where everything felt like a dream..a lucid dream. I don't personally think this is bad per se unless it affects your life negatively. If it's a good dream or if it's a nightmare will dictate whether or not you want to end the derealization. For me, it became a nightmare, and I stopped derealizing on antipsychotic medication.

If however you can still function to your satisfaction when you dream, I personally don't see a reason to try to snap out of it.
