creepy tiktok glitch

i was watching a tiktok, scrolled, then scrolled back and it started glitching. colourful and distorted pixels and all that all while the audio kept repeating eerily (like how you’d imagine a scene in a movie where someone’s getting hacked or their device gets a virus)

when i restarted the app it was giving me a tutorial again (how to swipe) and talking about updating security measures. never happened to me before just kinda freaked me out cause it’s late at night lol has this happened to anyone else?
