What is the meaning of my dream?

Today I had a dream of someone I hate being eaten alive by an alligator in a swimming pool... I can clearly remember the terrifying scream ... I woke up really scared of the verge of crying and very sweaty. I also felt very guilty for some odd reason.. And I am not the one who typically cries. I know it sounds ridiculous but I really would like to know what that dream meant... it has been bugging me all day
