Anyone have an inaccurate perception of themselves?

Something I've realized as I've gotten older, is that I'm incredibly bad at knowing how I'm perceived. A few examples; I used to think I looked normal like everyone else when dancing, but in reality I look like a robot having a seizure. I used to think I had a normal sounding voice, turns out it's way too deep and robotic. I used to think I wasn't socially awkward, but after seeing myself in video my mannerisms look extremely stiff and my movements don't look timed properly.

Is this an autistic trait? I thought I've read about this somewhere but not exactly sure, sounds like it is to me
