Some players aren't the brightest lol, that is amazing.
A ton of D&D spells pretty much amount to "I reject your reality...", in that they allow the player to dictate the fiction. They might not meet the ultra-strict definition posited by @Ovinomancer but I think they're close enough for me. Wish being the most obvious/powerful in that it can literally change reality.
With wish being a clear exception, 5e seems to have really curtailed the "spells actually completely change reality" aspect of prior editions. As in plenty of them change odds, plenty augment reality, plenty do whacky things like light the world on fire. But rejecting reality is more about looking at the DM and saying "nope, sorry that didn't actually happen..." (IMO and maybe nicer).
Under that definition, I think shield qualifies (kind of and that's really more about, again, changing odds). I guess revivify and raise dead are strong contenders. What other spells?
