Something really strange happened. Do you know why is it happening like that?

Today I posted an Instagram story of a video of me headbanging to some of my favorite rock songs. I posted 3 such videos but only 7 of my followers on Instagram saw them. I posted them at morning and its night now and the views didn't increase at all. Usually around 15-20 of my followers or even more view my stories but today its just stuck at 7 views. Its just like how sometimes very few to no people view my posts on here. Yeah my Instagram stories can be really silly and its mostly me headbanging to rock songs or curling my biceps. But I think they are ignoring my stories because yesterday was 20th July which was the day when Linkin Park's Chester Bennington took his own life in 2017 so I posted stories about it and posted 6 videos of his singing and live performances and saying how great singer he was and he was a vocal beast and etc. I could see many weren't interested in my stories because they weren't seeing all my 6 videos at the same time so maybe thats why none of them are interested to see what I posted.
