anxious dream

so i had a very horrible dream. a dream that had some girl as my wife and it was going smooth till she suddenly dies and her blood is all over the floor. her eyes are only showing, like bare fucking eyes with skeleton and this dream has been happening for like 2-3 days. she always gets in an operation and that somehow restores her body.

it just makes me so anxious waking up :( what could this be a sign of?
