Every now and then I will have an "episode" where everything feels like it speeds up in my head. When I'm reading, it feels like I'm reading 90 miles an hour, or if I'm playing a video game, it seems unusually fast. I'm not sure what this is. Sometimes it will last half an hour where everything like normal activities seems like it is sped up, when I know time is moving at normal pace. It's hard to explain, but that is the best explanation I can give.
