Have you ever felt like there was a past you?

I mean, like the person you are now and the person you were when you were younger are different people. You have different views and attitudes and just everything is different, but you feel like the same person.
I feel like this constantly and it’s like my past me is just screaming at me sometimes. I talk to her, too. It feels like I’m connecting with myself when I do, like I’ve found that piece that just seems like it’s missing from me.
Does anyone else feel this way? Am I not totally alone?
