I have had that happen to me many times. My doctor said they are a form of hallucinations and are called hypnagogic hallucinations upon waking up and hypnopompic hallucinations upon going to sleep. While sleeping you can experience lucid dreaming, they appear to be real and are usually very vivid and nice whereas the hallucinations are often frightening and sometimes you can feel paralyzed. But I found no matter which one I experienced if I concentrated extremely hard I could overcome and move past whatever the situation was.
Finding an excellent physician that specializes in narcolepsy will help you the most! Take care and know you are not alone in your journey!

You explained it well.
I believe it's called lucid dreaming where you are in control and yes many many times have I experienced this.

YES YES YES
And they are beyond weird!!!

Yes I have experienced that. However, it was because a friend told me to try a technique of telling myself before I fell asleep that I could do it. It worked!!
