My personality has changed significantly over time. I used to be a lot more extraverted just a couple of years ago, and I'd talk before thinking. I was an E. I used to also be more carefree, and go-with-the-flow and more experimental than I am now. I was a very clear P. I used to be more friendly, less confrontational, less hard-working, more creative, and more fun. Definitely more F than I am now. This was just 1 or 2 years ago. If you asked me back then, I would never have thought one's personality could just change like that. But it happened to me. I would say before, I was an ESxP.
I wanted to know if something like this is common, or have you heard of it? Or has it happened to you?
