I occasionally have a weird feeling that is very difficult to explain. The best way to describe it is that it feels as if everything moves very fast. I have had this a few times when I was younger and very occasionally in the last years. (I am now 18) It happenes especially when I am very tired or ill. In these moments, I realize everything moves at a normal speed, but at the same time it feels as if I move with 0000 miles per hour. Also, everything seems to be smaller and I get the feeling that everything is very urgent. I would therefore almost say it can be described as a kind of adrenaline rush, only without the physical symptoms. After about 10 minutes the feeling stops, but it really freaks me out. Do you know what it is?
