Just for context I have 3 identities that take over depending on my mood or circumstance. Child me, teenage me and adult me.
Child me sounds really young, more of a higher pitched voice , speaks really quickly and animated. Whiney and a bit moaney when things don't go her way. As most of my childhood is blocked out and I can't remember much, I dont always identify or relate to the younger me because I've subconciously blocked out all the trauma,  so it feels like there is more than 1 of me in my body that takes over at any given time depending on the scenario. I hope that makes sense. Anyway I digress.
Teenage me is very confident, witty and flirty. She can be really sharped tongued too if she is feeling hurt. Can drag arguments on for hours, full of insults, very exhausting.
Adult me is rational and level headed. Has learnt boundaries and how to protect myself from people who have hurt me (us) and wants to the best for myself and can think clearly and rationalise situations better.
I know they're all me but because I've blocked out so much of my life, I don't remember any of it so when things happen or a memory is evoked it doesn't feel like I lived it, it feels like a past me did so they take over when similar situations happen in present time. 

Does anyone else experience this? feel like you have more than one identity? I don't have anyone to really discuss it with so it would be good to have some insight into other people's experience with this kind of stuff.
