LDing, SPing Cant talk in a dream???

What first got me interested in LDing was when I was like 5 and I couldn't talk in a dream, I don't remember much but something bad was about to happen to me or some1 was trying to talk to me and no matter how hard I tried I couldn't talk. In another dream I was in bed about to have surgery but the anesthesia didn't work and I couldn't talk or even move. not long ago I had a flashback of this in a Lucid dream. I was in bed and I could barely move, so I awkwardly rolled off of the couch. it was dark and there was some1 in the chair beside my bed, they heard me hit the floor and was terrified saying "who is it? whos there?" no matter how hard I tried I couldn't talk to say its just me, don't be scared. I just sat up against the wall on the floor for a few minutes while they kept saying that kind of thing until I woke up, this instantly made me remember those dreams more vividly than I have for yrs...

Can anyone help explain this or anything?

You're afraid that you'll wake yourself up. That happened to me when I was starting out too. Just force it.

really? thats interesting! Is it really that simple because that sounds likely.
