Recurring Lucid Nightmare

Why do i have this Recurring Nightmare?

Okay so I have this dream a lot where I can't open my mouth or sometimes have slight problems moving around. So my latest one was where I woke up in my bed at my parents house and my dad came in my room. I forgot what he did but it was mad creepy then I realized I was having this dream again so I tried to talk but I couldn't. So I ran down to his office which looked suprisingly like how I remember it. Then I tried to type in on his computer what was happening and he just kept staring at me. The whole time I was straining to wake up. Eventually I did. Anyone know what this means I am so tired of it. Sometimes it gets really intense.

Most of the time it is a semi lucid.

Also it has nothing to do with my father this was just the latest scenario. please help im very sick of it.
