Hallucinations? I think Im in TV drama when I get drunk?

Is this normal? A few months ago, I thought my boyfriend was a character in tv show (Arrow) and that I was “Oliver Queen” himself. I’m female also, so this doesn’t make sense at all to me. I do remember it, so I wasn’t blackout to my knowledge. But I was acting as if I had a mission or something and that I was going to get caught?

Ive had situations similar to this but not as vocal, thinking I’m another person when I’m barely tipsy even. I’ve caught myself, and it’s REALLY creeping me out. Im not sure what to think at this point.

Am I a compulsive liar or am I just nuts? Its really weird because I actually believe that I am THERE. In the scene, of ANY show I watch. Any advice would be helpful.
