Facebook Page Jumpscare (Potentially by Chucky)

So, the situation is set when I was a little, probably like 5-9 years old (2009-2015) when it happened. I was asked by my cousins to go their house to see what is on their computer and since I wasn't have any computer at that time, it was so exciting for me, with a smile on my face i agreed with it right way and went to their house happily. And, once we arrived at their house, when I saw the computer, it was one of the facebook page opened in it. After that, I saw them signaling each other to do something or to pressed something, since I was still innocent at that time, I looked at the computer like most of the time. This where they pressed something and suddenly the facebook page screen is got torned by something ghost (possibly chucky, cause I probably mistaken) like it's gonna get out of the screen and it scaring the sht outta me. Since then, I got traumatized by this sht for such a long time. So, I try to have a search about this like on everything but I got nothing. And, when I asked one of my cousins, she said she already forgot about this thing and told me like I was delulu and this thing never happened even once, but the thing is I'm not, It's haunted me days, like how can I forgot this sht. I hope everyone in here could prolly shed a light on this things, cause I know that this is legit happened. But, It's okay if you guys not getting it, at least it's not just me that experienced this.

And by the way, I really sorry if my english is bad since english is not my first language. Second, Is that I just discovered lost media recently (like this year), since one of youtube video about this topic popped at my page, and here I went shooting my shot about something I experienced once. Hope you guys could help.

Thank You...
