Super abusive Ad seriously what the heck was that (i need someone to tell me im not the only one who saw that horror im really not doing well about this)

ok hi ! yesterday night at 3 am i got what i think is the worst ad ever,, it was an Ad about a decapitated cat i think or something like that,, with horrible images,, i cant say if it was a sensibilisation video or a promotion for anything,,, when i saw the images i just wanted to vomit,, chill down my spine,, i was just horrified and wanted to just put my video quickly,,,, i didnt took a video of it i was way too scared and didnt felt safe for the rest of my night,,,, slept super badly,,, does any of you had this ad before ? what is it about seriously ??? and how the heck is it an ad on youtube !?
