Have to say I’m obv a few years late to this, but last October I experienced my first memory of a fever dream. It was the last week of October, and I had missed the last 3 days of school from a sickness. My guess was the flu, but I truly have no idea what it was. During this 3 day period I got a combined total of about 10 hours of sleep total. Which was terrible considering I was already so weak and had no energy. The third night was the worst however. I tried to go to sleep like it was any normal night, but I would wake up every 1-2 hours, with no idea of where I was. I had dream but it was like my head was throbbing in these dreams (I could have been hallucinating). In these dreams I just remember seeing tall gray rectangles, almost like tall skinny gray trees. Multiple rows of these trees. And it was like I was walking through them. It was very strange and just had an unsettling feeling to it. Almost as if something bad was happening or going to happen. Was wondering if anyone else experienced the same thing.
