What happened-Was I just dreaming?

This has happened to me and the answer as far as I can tell is very clear. You were asleep and dreaming and that is why you could not move. That is what happened to me. These dreams can be realisitc and a little scary, at least it was for me. Now you move just fine right. And so could I, after I woke up, but while I was dreaming with no amount of effort could I move or open my eyes, no matter how hard I tried. The thing is you dream you woke up, but you really haven't.
