One of the bigger ones I get every now and again is I'm running down a park walk way and there is a guy on a horse chasing me down and I try to scream for help but I can't make any noise and he catchs me with a lasso.
I had a nightmare where me and my bf went to stay at like this rustic bed and breakfast that was run by really hot chicks. There was a bunch of my friends there and at first it was really awesome. Then, the chicks left and everyone was kinda hanging out and I noticed that the walls wre covered in paintings and mirrors. I caught a painting moving out of the corner of my eye and looked into it only to feel my mind being sucked into a tunnel made of paint and pretty colors. I somehow pulled my mind away and looked around to see everyone I know being sucked into the paintings. I kept trying to break them away, but I couldn't and everyone I know lost their minds.
I guess it's prolly symbolic or something. ******** it
I get nightmares usually just out of nowhere in my dreams. I think its a nice dream where you're so relaxed you can "feel" the dream but then something unexpected will happen and then I freak out and my spine pretty much wakes me up.
In a dream I had, it was all good, I needed to go to the bathroom real quick, on the wall I find a tiny spider, grab something to kill it with (no big deal), I get in close then it hisses at me, Im like O.O wtf, we have weird fight things, it gets on me, I freak out and try swatting it, my spine gets that excited feeling thing and I wake up and Im like waving my arm around and smack myself in the face.
Maybe you just aren't remembering your nightmares? Or you are the unholy spawn who fears nothing.
Watch the human centipede. Its terribleness will induce nightmares.
