Am I in the wrong?

I have this aunt who I never really got along with but for the most part we’re cordial. Well this past year has been intense for my family as my grandmother (her mom) has gotten really sick. My aunt lives in another state so she’s been flying in more often to see my grandma. In my grandmas apartment, I have a bedroom and it has a few boxes of my things in there. My aunt decided to rummage through it without asking me and then after finding things she liked.... she asked me if she could keep them LOL. Then today I find out she’s flying out with her husband JUST to go through my stuff in that room. I’m not even joking. Just to go through my stuff. I told my mom I would prefer if they didn’t touch my things because I don’t want her to find personal items I have.

Am I wrong for telling her she can’t go through?

*the reason why I have some boxes there is because during covid I had to move and now I’m moving out again. I give my grandma $$ to keep my stuff there but it’s always been my bedroom*
