Ok, I know that I'm really late on this post but I always wondered about this same feeling that I would get from time to time. Just like Strings55, I thought that I was the only one who had this feeling. It doesn't happen much but when it does, I find it very amusing and kind of funny (in a weird way)...Just like you said Toller, it just feels like everything is running in an ever-so slight "fast forward" motion. People are talking faster, movements are faster, music that I was listening to seems to be playing at a faster tempo, you get the point. I always theorized it to be some sort of panic attack and believed that my heart rate and respirations would be increased during this time. Like you said Toller, sometimes it would last for a few minutes; sometimes about 10 minutes or so. So the next time it would occur, I would monitor my heart rate and breathing pattern. And I found out that although everything seemed to be moving perceptually fast around me, my heart rate (62 bpm) and respirations (14 per min) was actually normal when it did occur again about a year ago. I made sure that I counted for a full minute with a watch that had a second hand. I cope with stress very well and when it comes to many things in life, I am open-minded but also realistic. No psychological problems run in my family and I consider myself mentally well-rounded and physically healthy (no blood pressure problems at all; BP 120/80); although I have a quirky, dry sense of humor. So if you have any other further insight on this, please let me know. Also, the visual "warped" optical feeling you get sometimes, I also get them too. Just not at the same time with the altered time perception. But I do get them more often than the "time thing" and I just thought that it was eye strain (although my eyes were not in any sort of pain or discomfort). I would describe it to my friends as if my depth perception was extremely altered and it was hard to tell how far an object was even if I know that it was close by. People that were close to me just looked smaller than they are supposed to be. This would be quite annoying especially when I'm playing basketball. It was just so weird because the rim and everything else seemed so small and far away! Imagine trying to shoot when you are "sensing" that. Sometimes I would just close my eyes (but not on the basketball court) and it would eventually go away, although I don't think it mattered because it would go away in time. My friends thought I was weird because their version of eye strain wasn't like that. The only person that I knew who experienced that was my ex-girlfriend. She said her visual depth perception anomaly happened a lot when she was a kid, but just like me she thought that she was the only one who experienced this.
Ok, sorry for posting a really long thing on this but when I found this post, I was really happy to find out that I am not alone on this.
