Waking up into a dream--the other reality

Hi guys,
Maybe someone can explain some of the crazy stuff I've experienced. But for this I'll just ask about one thing.
I have secret dreams.
We all have them. The ones we don't remember. We dream several times a night and remember maybe two at most.
I can sometimes sense my secret dreams.
Sometimes, after the main dream winds up, like a movie finishing, I shift off to a different plane of consciousness, like entering a curtain to a back room. Like waking up. And sometimes there are people there, who've been waiting for me to arrive, to tell me things.
Two years ago, it happened the same way several times. I'd wake up into a room. There were people there, men and women, and though not familiar, I kind of felt I knew them. They'd talk to me, tell me things.
I was lying back on a reclining chair, a little like at the dentist's, and they'd tournequet my right arm, and inject me.
This happened several nights over.
And this did not feel like a dream, but like I said, moving into some other space in consciousness.
I can't recall what would happen after.
But after waking, for the following day, I'd have literally HUNDREDS of feelings of deja vu. The smallest things set it off. The way light broke between moving leaves. Picking up a pen. etc. Within seconds the feeling would wear off. One day it got so bad that I knew if it happened much more I'd start to lose my mind.
After a while I figured out what was happening.
I had dreamed the entire day already, in a secret dream. That's why everything kept sweeping over with such jarring recognition.

I know this isn't your average psychic phenomena query, and the few I've spoken to about this feel it's far past the realm of their experience or understanding.
Any ideas?
Sorry this post was so long, but to use less words wouldn't have painted the picture so well :)
