I'm not sure I had any explicit mechanisms in mind. These were gut reactions. But I can try to elaborate on the reactions.
With dizziness: you've spun to get dizzy and now you're spinning more and that's obviously just going to get you more dizzy.
With stitches: the problem is a hole in your skin and you're trying to fix it by adding more holes and running some thread through them? Thread does not belong inside your body!
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
