The most annoying advertisement that I have ever seen is a video ad of the game Dead by daylight . I was playing a game on my mobile, and came across this ad. The audio and visual nearly gave me a heart attack. I'm not a fan of horror genre. This unexpected ad, especially the audio, is so annoying that I turn off the audio completely on my phone to avoid any future nasty surprises like this.
The witches of Halloween, Oh oh, The scariest I've ever seen, Oh, Oh. Fly through the night, Give me such a fright. The witches of Halloween, Oh, Oh.
