lucid dream nightmare

I'm well aware that what you see while lucid dreaming is a hallucination. Still doesn't undermine the fact that what you can see is undeniably creepy. I was laying in the darkness, I am rather sleep deprived because my allergies are trying to kill me and I can't breathe through my nose.  It's 5 pm and I am attempting to go to sleep because I only got 3 hours of it last night. I turn off the lights, there's only dim lights from the TV and wifi boxes. I am about there, things are fading and I'm almost out. Right then I see a black shadow standing about 3 feet away from me it appeared to be in the shape of either a wolf or a really large cat with pointy ears. Behind it, I could see someone behind the curtains that appeared to be human but I don't know. The cat thing moved unnaturally and came up to the side of me and I couldn't move. It felt like it was in my face. Finally I snapped out of it and everything was gone. There was nothing and I was sitting up in bed.
