It's not about trying to escape from something. But if you go out to a club/pub or something, after a few drinks you become much more open, and less shy etc. You start to care less about what peoples think and more about having a good time, so you're more likely to dance or talk to people you wouldn't normally and such![]()
So you are escaping from your own persona....
What makes you feel shy or worried about what other people think when you are sober?
