personality change?

When I got drunk the other night I genuinely believed I was a different person.

For context I’ve been binging Archer. I went on a night out and wandered off then like argued with security about how I was Sterling Archer and how I need to use the phone to call “mother” because she had blacklisted me and I need to use my card (I didn’t even have it on me. I have very faint memories of that night. My main reason for concern is that like, I’ve done stupid shit while drunk, I’ve lied to people and shit like that, but I remember genuinely thinking I was the character.

Is this something I need to be concerned about?
