A strange man in front of my house

Date: 10/4/2021

It was a strange man whose face was barely visible to my eyes. He was outside of my house at night. In this dream, my house unreasonably had a lot of glass doors and no fence, so practically the inside of the house could be seen by the outsiders, including that man. He didn't try to break into my house or anything, just standing there and watching everything with unknown intentions like a stalker. He didn't have a weapon, but his figure alone frightened me. I did a futile attempt to close every single glass door in my house to keep him from entering. It felt like years to close them and my anxiety got worse when I saw him, still glaring at my house but never actually moving from his place. What does it mean? I still get creeped out by recalling this dream.
