I don't partake in any kind of drugs outside of alcohol in social settings. I do however have an anxiety disorder that comes with a lot of panic. I always described myself in the throws of panic as feeling like I was playing a video game. It's a very surreal experience to feel like you're driving a car except your body is the car. You think right arm move and it does, but it doesn't quite feel like yourself. Very strange experience. Incidentally, it took me about 2 very long years to get a good handle on it where I'll only have an episode like that once or twice a year.
