Studying literature in grad school with a non-related major

[moderatedbliss]

For those of you are applying or have been accepted into a lit/comp world lit program even though you had an irrelevant undergrad major, what has your experience been like? Any precautions, warnings?

Even if you have not, is there anything you feel I should consider? In general, what is applying to an unrelated graduate field like?

I am a Sociology major with great grades, LORS, and research experience, but I can't help but feeling that literature is where my passion is. I've considered studying the sociology of literature, but feel that may be too narrow.
