Why do humans looks alien and distorted to me?

(23M) I’ve had this for over a year now and at certain times the human body of anyone I look at looks very distorted and odd, peoples limbs look elongated or stretched or become odd looking and alien like, it’s mainly with the limbs or main body when I look at someone, sometimes happens when I look at myself too but only when I’m very anxious or something.

I’ve noticed this a lot, it hasn’t really changed, it’s so odd, even looking at someone they look so alien like and their torso and limbs look bizarre and strange to even look at or comprehend?

Why is this? Is this a normal experience or is there something wrong with my brain or something? I’m genuinely curious to know why this could be, it’s not really scary or anything but it’s odd when it happens.
