TikTok shared a random video when I wasn't online and didn't even watch it

Yesterday in the middle of the night when I was most definitely asleep and my phone was off, a video was shared to my friend. I thought it was my mistake at first before I saw the time and the video, which I had no recollection of. I searched in my activity centre and watch history and it never appeared, though earlier in the day I watched a video from the same creator.

Has anyone had a similar experience or can anyone explain why this happened?
