When i look in the mirror i feel like two different people...?

I know this feeling!! I always feel like someone else, not my reflection. I've talked while looking in the mirror and I don't like to see myself talk. It could be an alter-ego thing. I always imagine my "ideal" self in the "here and now". Then, I look in the mirror, get disappointed, and say "This is not me!"

Tried "depersonalization disorder"?

your lucky i am the same but different in ways
when i talk to myself or ask a question he answers and he keeps telling me that i can't trust anyone and when a guy started beating the crap out of me i tried to fight back but couldn't and then i fell to the ground bleeding he came out it was as if i was unconscious but could see what was happening my body stood up and i heard a voice say don't worry and laughed and i saw myself beat the crap out of the guy until he was unconscious.he always enjoys beating the crap of out of people it is like he has a blood lust or something its been like this with him for as long as i can remember.i tried to live my life ignoring him for a year and started to go insane i don't no what to do if i let him back and start talking to him and trusting him like i used to i will end up a loner again because the people around me were scared of him but if i go back to ignoring him i will drive my self insane what do you think i should do?

This happens to me as well and if I let it get very far, it will scare me.
This also happens quite a bit more dramatically when I look at people that I know well and are very close to me. Either I'll be staring at them or I'll suddenly look at them and get a very unnerving feeling that I'm seeing them for the first time. I'll start thinking in my head like: "This person is my friend" "This person's name is ____" This person's name is ____???" "I KNOW this person??"
I'll let myself keep going on like that until the person is almost unrecognizable and I'm sittin' there freaked out.

I get this feeling too, except it's not just when I look at my reflection - I actually talk to myself. It's like my older, wiser alter ego talking to me through the mirror. And it does feel like another person, as you say. I don't get scared by this though. Why are you scared?

This might not be something that happens to everyone, but I've read a couple of stories on here about feeling distance from their body/reflection, so you're not the only one.

it's normal

It could be a habit picked up from lonlyness. If not then there are conditions of split personality disorders. Depending on your age you could manifest symptoms at any time. It usely develops in the early twentys/late teens. Anything beond or befor that isnt common but still, not imposible. Best you go to your Dr conserning your mental health and see if its anything to worry about.

Most people talk in the mirror, complementing, judging and sometimes insulting there image. This is normal. But because youre under the influance that there may be another consiousness, differnt and detached from your own. It sounds much like a symptom of a personality disorder. Espesily because you feel you have to self denie its existance. Still, go see a Dr about it. Theres probibly nothing wrong and may turn out to be your imagination.

Good luck.

You're nuts
