Have you ever been having a non-lucid and at some point in the dream you get in a bed and go to sleep.. shortly after, waking up into another dream? Then possibly becoming Lucid?

I've had this happen a few times. Sometimes I'll even meditate in a non-lucid dream, then I will enter a LD from the meditative state after closing my eyes. Just last night I went to sleep within a dream, woke up in another dream, did a reality check and became lucid. I got excited, & knew I was going to wake up. I focused on staying asleep. After focusing I tried to move and I could not. I became paralyzed (my dream body did) and woke up.

Have you ever had a similar experience before?
or..
Do you know why or how i became paralyzed?
