Honestly it's pretty funny to me how people think 4d is all strange and terrifying, when in fact it's (to the degree that it can be said to actually exist, since it's theoretical/mathematical) pretty "simple" and just headache inducing to try to wrap your head around.
like your mind wouldn't shatter from being moved through 4d space, things would just look completely nonsensical and impossible, it's no more lovecraftian than subatomic physics. It's just Kronk saying "by all accounts, it doesn't make sense".
