Can you even *do* 15- second horror without gross-outs?

I saw this – ‘this’ being a competition to come up with 15 second horror films – but I’m not putting up the video because it got to gross-out in #4 and I could tell that #3 was going to be body horror.  I’m not knocking either*, but I do wonder: can you scare somebody via just mood and atmosphere, in 15 seconds?  And not by jump scares or other physical reactions, either: I mean straight-up emotional/intellectual terror.  I suspect that the answer is ‘no,’ but I don’t know that it’s ‘no.’

*I’m also not watching either tonight.  Some days I’m in the mood for it; some days, I’m not.  This would be ‘not.’
