"I feel a presence near my bed....I realize that I am paralized."
This is a common occurance...just be lucky that you don't see an Old Hag sitting on you!....the legendary "Old Hag Syndrome" that a lot of folks have. Scary shit!
"...movement gets really hard like I am moving through liquid cement..."
Another common thing, like when you're either running away or trying to throw a punch at a bad guy trying to get you in your dream! I hate when that happens!
