I couldn't move when I woke up?

So it's 7 AM now and I tried lucid dreaming because I woke up at around 6 AM and had nothing to do.
So after I dreamed of helping some girl out with her iPhone (I don't even know) I decided to wake up.
When I tried to wake up my muscles felt like they were being pushed down to the bed and I couldn't move. I kept like falling back to the dream and ya.
Now my arm muscles are feelings a LITTLE strained.
What the heck happened haha.

Sleep paralysis. It's common. Look it up.

That used to happen to me too. It's nothing to worry about, just a dream.

It was sleep paralysis
It happens when you awake while falling sleep

I started using it just a couple of weeks a go and am already seeing some serious results.
