I dont use a real weighted blanket but I do use heavier blankets, I cannot sleep with sheets or nothing on (unless Im totally exhausted). I must be covered neck to toe and even tucked under my feet. My favorite thing to sleep under is the top cover (ya know, the nice one that you shouldnt 'use') or fleecey like blankets that are super soft and cuddly. But plain light blankets, no thank you. Even if it's summer, a sheet is just so not enough to make me feel secure. You know how most kids during a thunderstorm pull the covers up right to their face? Thats what I do!
