What is this!?

I don't know if any of you can help me with this, but I decided to post it anyway.

Ok, this rarely happens to me (maybe once or twice a year), but I sometimes experience this strange sensation when I'm doing some kind of activity (like going on the computer, playing video games, talking to someone...etc.) and something in that activity triggers a feeling of EXTREME deja-vu that's related to my dreams.  After that, my mind is flooded with images/feelings from my dreams and I get sick to my stomach (to the point of vomiting) and so dizzy that I have to lay down.  This feeling only lasts for about 2-3 minutes and when it stops, I'm pouring sweat and I feel light headed.  Like I said, this hardly ever happens to me and when it does I'll usually experience it 3-5 times during the day.  (Its already happened twice today)

The strange thing is that I have no memory of these dreams at all (even after I experience the deja-vu).  All I know is that they're not typical dreams.

Does anyone know what this is?

Yeah, I probably should ask my doctor.

Thanks for the reply.
