“Bare in mind” is a misspelling of the phrasal verb bear in mind, which means “remember” or “consider.” The verb “bear” means “carry”; the idea is that you’re holding something in your mind. The verb “bare” means “uncover,” which doesn’t make sense in this context.
People also confuse “bear” and “bare” in other contexts, such as in the phrase “bear with mạ.”
