I do not believe in the supernatural, magic, ghosts or anything like that. However, I can be very superstitious about tempting fate and won’t make jokes or flippant remarks that could be interpretted as such.
For example, my partner made a dark joke about how she’d rather have cancer than such and such. I begged her not to say such things, not because the thought of her having cancer upset me (although it did), but because it feels as if saying stuff like that could make it happen.
IDK whether to call this superstition or what, but one foot always has to be the first foot off the stairs. I sometimes count the stairs if it’s easy enough to ensure I step on with the correct foot so I can step off on the correct foot.
Though, I guess you could say me always wiping my hand on my jeans or touching something else before touching a metal doorknob/handle as a superstition as well, maybe.
