Quick question

[heavy bison]

For context, only the right side of my body shudders and tenses very briefly when I am anticipating the sound of an explosion in a video game or a movie, and it's been confusing me for years xD i just want to learn why this is

[proper charm]

thats probably not a tic but a reflex

pretty much everyone does that /npa

like when you're anticipating a loud noise you tend to tense up. thats normal /g
