Scary Dream

I made a scary dream yesterday, just before waking up. The dream was about I was in the car, at the unknown deserted place. Suddenly there were few people walked towards the car and opened the door, and tried to grab me. I woke up after this. This is the first time I have such a vivid dream. Previously I almost couldn't remembered any details after I woke up. If not, most likely I couldn't determined if it's a dream, or it's just some wild thinking of mine during half sleep.
