Mine: I was 5 years old and my parents had this old brushed silver stereo receiver. In the dream this thing screamed at me in an extremely booming, terrifying voice. I cowered in the corner, curled up in a little ball while it continued screaming.
First one I can remember is a ridiculous one I had for years as a kid. I’m up on a high tree branch inching my way towards a giant bird’s nest. There is one huge egg in the nest. It cracks open, revealing…
…a dalek screeching “EXTERMINATE!”. I awoke sweating.
I have a reminder on my Calendar app for the anniversary of the event that Stanislav Petrov prevented - September 26.
The first nightmare that I remember was when I was 5 or so, but it didn’t feel like a nightmare. In my dream everything was black and white, with snow on the ground, and the sky was completely black. There was no visible source of light but I could see perfectly well. Almost like some the old Krazy Kat comic strips. I was outside in my snowsuit with my short toboggan. Then I met a tall white skeleton-like figure who did not speak, but I knew him to be “The Boogyman” and allegedly an object of great fear. Nevertheless, he turned out to be a great guy, pulling me around in my toboggan, and we both had a grand time playing in the snow. Not scary at all.
(Or maybe he was Johnny Winter, who would’ve been a teenager at the time.)
I would have been 3-4 years old. I was suddenly eaten by a dog: inside the dog it was round and metal (like one of those metal tube slides). Through the dogs mouth I could see a nursery-worker asking me if I was okay (obviously not!) before the dogs mouth closed again - presumably trapping me in there forever.
Earliest nightmare (sort of) I can remember was around 5 years old - my top sheet was ripped, creating a long strip of cloth, and I was a restless sleeper. I woke up in the middle of the night, totally bound, unable to move. I was petrified and screaming until my parents came in and “rescued” me. I felt the impact for years - always hating the confinement of sleeping bags, even when camping on cold nights. I would always leave the bag unzipped.
Totally off topic (in an off-topic category) I had a scary and simultaneously hilarious nightmare in my early twenties. In the nightmare I was at a summer camp overrun by zombies. A long, epic, bloody battle ensued, and I end up being the lone survivor in the entire camp. I climb to the showers at the top of the hill, strip and shower off all the blood and sweat as all is finally peaceful. Classic horror film false ending. Suddenly I hear a resurrected throng of zombies moaning as they climb the hill to get me. I snap and scream “I can’t take this anymore!”, and I run naked from the shower and hurl myself from the top of the hill into the horde below. Just as I am about to land and face certain doom, I hear one of the zombies shout in a deep resonant voice - “I want his testicles!” I woke up with my heart pounding, and I was literally laughing at the same time! Good stuff.
