The most horrific dream I've had is so bad that I can't tell it in it's entirety on this site.
It had to do with me getting assaulted and worse by someone I apparently knew. It's a recurring dream as well. I can't tell if it's just flash-backs of an incident that happened when I was 15, or something else... Either way, it still bothers me.
When I was younger I had a dream that showed up for about a month, around Halloween, every year that was me being chased by a T-Rex. Usually it included someone/thing or person that didn't exist in reality, but was killed/destroyed, and was seemingly important to me.
Years from now I am a Special Forces sniper trying to stop terrorists from detonating a nuke in the Horseshoe Coloumbus my friend goes to shut off the bomb but is killed by a moltov cocktail then the nuke goes off and millions of people die in an instant.
It was a very bad dream. I woke up, I heard moaning. I looked to my arm and saw my skin was green and I was in more pain than I was in my life I was a zombie. I screamed while I felt a gnashing. It was rats feasting on my leg. I screamed while men came in. I said "Thank God" when they shot me. I couldn't die. All I could feel was pain. I couldn't die. That's when I woke and screamed.
probably the one i will have tonight, internet gets freaky when you go places that arent meant to be gone to. You cant unsee what you see, even if it is fake.
a certain type of anti-malaria tablets that i had to take gives you vivid dreams... and i had three of them and two were nightmares... i mean vivid nightmares. so first off i am living in basically jungle at the time.. first dream was me walking with my friends in the jungle i was sleeping in.. suddenly each one disappears after each other until i am alone. i then turn around to find all my friends only for me to realise that all of their heads are at an odd angle and they move like they were puppets. i run, they give chase and eventually i run into someone i knew.. he smiled and i smiled in relief only for his skin to peel back for the horrible figure inside to emerge.. i then run some more only for that creature to constrict me with some kind of tongue and trip me. the puppet horde than catches up.. they crowd around me and start to... that was when i woke up. my other one was even worse but it is only scary to me probably not for you guys
