I’ve had the exact same experience and I thought I was the only one with this! It’s almost as if you know there is nothing wrong but everything is fast and spinning! When this is happening I talk really fast in my head but I don’t have control over it! I only half finish sentences in my head while everything is in fast motion! I usually end up staring in the mirror making confused faces during these episodes until it  passes! Also I try to ignore it but I end up doing a lot of action and over doing my makeup for example! Everything I do seems wrong when these fast motion episodes are happening and it’s as if I’m constantly looking for a reason why I’m doing these actions, it’s almost like an urge to do something but your not sure why and it’s an adrenaline rush but your still exhausted??? Anyone know how to stop it or prevent it! I am assuming it has something to do with anxiety or being in a state of panic even though everything is okay??
