I think im going crazy

Im pretty sure someone is living in my house so heres the thing I moved cities for college and ive been living in dads house its a duplex but each floor has a living room kitchen bathroom blabla and I only use the first floor kitchen for the second floor I use it as storage ( its important for later) and also theres like this creepy room (?) but its above the bathroom I cant reach it apparently its used for storage now heres the creepy part im a very forgetful person and sometimes I would wash the dishes and when I go back to the kitchen someone wouldve put everything right back to its place but not in the way I usually do it also my soap would disappear and I would find used dishes in the second kitchen so many weird things my clothes would be all over the place and stuff disappearing but I just thought I was being paranoid even when I hear breathing at night cuz even when I search the whole house nothing . Now im back with my parents and my uncle called yesterday he said he swung by the house and found all the windows open and it rained so yh the thing is I remember clearly that I closed every window since im travelling I literally triple checked so yh I think someone is in the house and idk what to do .
