Did I imagine a spark at my iPhone X’s Lightning port?

This is an odd scenario. Please bear with me as I’m terribly tired, but my anxiety is getting the best of me.

I was about to turn in for the evening & I was about to plug in my iPhone X. No lights were on, except for the glow of the tv.

I was about to insert the iPhone X’s Lightning cable in; it was literally at the opening of the charging port, when I thought I saw a spark. I didn’t insert the cable. Upon looking again, I thought I just saw the dull reflection of the tv’s lights on the metal edges of the Lightning cable.

I inspected the cable and the pins were perfectly fine - no black residue. The metal edge of the Lightning cable had some black on it, but my finger was able to wipe it away as if it was just dirt, debris.

I know there won’t be a definitive answer to my question, but from your experiences - do you think I saw a spark, or just a reflection of light off of the metal edges of the lighting cable? Also, the opening of the iPhone X’s charging port - is it plastic, or metal? I thought that might play a role if static discharge was an issue.

A few things worth noting: I wear glasses, but as I was plugging the iPhone in, I wasn’t wearing them (my vision isn’t too terrible). I did eventually plug the iPhone X in and it charged just fine (the cable and charger seemed proper).

Any constructive comments are welcome.
