So I was just watching a bunch of youtube videos related to dreams and dreaming, as it is a very interesting topic.
I remembered that, when I was ~11 and below, and had dreams, or nightmares when I had a fever, very consistent, oddly terrifying nightmares. They were always abstract, without concrete figures or beings, just "feelings" expressed in a visual form (although not actually seen, obviously).
I remember having several nights with a fever, or maybe even without a fever. having a consistent nightmare with what I remember to be dinosaurs laying eggs, and I would come out of the eggs, and I was confronted with mortality somehow. Like, in that recurring nightmare, I was confronted with the idea of mortality. I remember everything looking oversimplified, with earth like colors (green, blue), and somehow "things" (I remember them as dinosaurs for some reason) were informing me that things were going to end. I would normally wake up screaming and crying. That might seem like something not so abstract, but it really was completely abstract, unfortunately I don't remember it to well... It's just a very vague memory now. It could have been aroung the time when I was actually confronted by the idea of mortality when I was probably around the age of 4 or 5. No one had told me about death until one night when my mom's now deceased and ex boyfriend told me something about someone dying, I proceeded to cry and I think I said something along the lines of "you mean there's an end?" something like that. heh.
I also had nights (these ones were always while feverish) when I would have nightmares with hundreds of thousands, millions, maybe even billions of machines, gears, and pumps running, almost like an extremely coomplex interior of a piano. Everything always moving, with the feeling of, well, a fever (warmth mostly). It was so wierd. I guess it could represent confusion. But I think fevers influence your sleep (and how you dream). In another nightmare, possibly the most recent one I had with a fever consisted of very video game-y kind of feeling, I distinctly remember it resembling the original starcraft and diablo, having not played diablo at that age (I was probably 11 or 12) it was probably something having to do with me playing starcraft when I was like 8 (not that that's a bad thing). I woke up screaming a looot and I remember just waking up and still feeling the dream in my thoughts, like I was half in reality, and at the same time inside this red hot dream filled with pixelated aliens (though they were not exactly zerg like, they were just shapes, but my brain associates it to the zerg). I was still int he dream and panicking while in my mother's arms lol. funny how I can remember it so vividly.
I know that we all dream every night unless we're snoring (apparently humans are not able to dream if they are snoring, so people who snore while dreaming constantly do not dream at all), but I rarely remember them nowadays, my sleeping patterns got all messed up during the summer because, well, dota 2. Now I rarely sleep for more than 7 hours, and I normally go to sleep at 2 am-5 am.
If anyone actually bothered to read this, tell me about your recurring dreams and nightmares, and maybe the ones you had when you had fevers, if you remember them!
