[Serious] Reddit, what is the most terrifying nightmare you've ever had?

This was last night's dream. I'll try to keep it short, since it's not really that scary and I can't remember all of it...

It started with me watching YouTube. The video was of a German teacher filming his students. One of his students had gotten beaten up. The teacher encouraging the student to go beat up the other kid and they were now speaking in Spanish. The kid runs off with a knife to beat up the other kid. The teacher (still filming) sits at a picnic table and sets up his laptop. Next to the laptop, he starts carving weird symbols in the desk and crying about his wife he cheated on. His laptop starts playing a YouTube video with some girls on it. Suddenly, his screen starts to crackle and change colors to red. When the screen comes back, it says 3:00 AM on it.

Suddenly, I'm at an elderly couple's house. I've never seen them before, but I think I was planning to live with them for a little bit. The nice lady shows me around a bit while the man goes outside. She leads me to a room with a large TV and a Nintendo 64. I sit down to play, the elderly lady letting me know she'll come for me when dinner is ready. I get lost in the game, a few hours go by. I open the door and the house is very dark with only the moonlight shining in through the windows. I walk down a narrow hallway to find their cat hissing loudly at the old lady whose mouth was open wide like a snake. She was yelling in a deep and powerful tone, her eyes black. I run out the house, suddenly in my own yard that I have in real life. There's a large creature that looks like a bobcat with deformed legs and antlers. It runs off.

Next, I'm in a prison cell. I see two men and a woman that seem to be fighting over a young girl. Their pulling on her body, yelling at each other. It appears the woman is trying to keep the men from taking the young girl. I run to a sink and grab two forks, stabbing the men with them until they're covered in blood and release the girl. They run off. The woman turns to me and starts to thank me before she screams out in pain. Reaching down, she pulls out a fork. The little girl had stabbed the woman and was crying, saying she didn't want to be taken away with her, again. That's when I notice the girl was in the German teacher's YouTube video, and she died in that video. The girl starts screaming at me, and I run out the door back to my own yard. The giant creature is there, chasing me down the driveway.

I wake up, I'm in my own room. Rubbing my eyes, I look under the door... to see a pair of eyes of the little girl looking back at me. She reaches under the door and I scream, suddenly waking up again. Now I'm in my room, but the lights are red and the wall is covered in strange symbols while I go crazy.

I wake up... For real this time! Like, I'm actually awake and safe in my bed with my laptop. I look at the time on the laptop, it's 3:00 AM, just like on the teacher's laptop. Sounds like a cheesy horror story ending, but it's the truth. I (a 24 year old that served 4 1/2 years in the USMC) turned on SpongeBob and went back to sleep after a few episodes.
