Ha, I can't even count how many times I've woken up with my dog looking at my face like that It usually scares the crap outta me when I'm all tired and out of it, but I think she's just some kind of sadist and likes seeing me suffer.

You're crazy for wanting scary hallucinations I wouldn't wish them on anyone. But for me, the times when I usually see creepy stuff is when I'm in a bad mood or nervous about something, also I had my first vivid lucid nightmare when I fell asleep with the TV on in the background playing some horror movie. I could still hear the screaming from the TV in my dream.
