Fading into reality in the morning...

There's been some mornings when I've been disappointed to realize I'm awake.   That realization can take  some time too, like today: I was gathering up my energy to go into the next room and type an address into the search engine, when I realized that no, there weren't any giant, bioengineered sheepdogs in reality.  I hadn't spotted one in the field on the opposite side of the gorge next to the university, and followed it.  And the effort I had spent to sneak around and read the company's web address off the side of the van was wasted.

Has anyone else had dreams that have lingered well into waking time, that refuse to release their reality quickly?
