Sounds more like it may have been a blessing for you--those sound frightening indeed. For me, it's been a mixed bag. The more lucid the dream, the more likely it was precognitive. Although I have had sleep paralysis. It was weird, though.

I woke up, but couldn't move, and was barely awake, like I was trying to fight off the effects of a drug, and I couldn't move or do more than moan. I swear I thought I saw a shadow in the room of a person. Eventually, I fell back into an uneasy sleep. When I woke up the next morning, my neighbor told me she'd seen a black car pull up about 4 am, and three dudes in black get out and go into my back yard and around the side of the house where my window was. She said they were gone for 10-15 minutes, then re-appeared, got into the car, and drove away.
