No one cleaned it when I went, but someone cleaned it before I came back, so I put a broom, and it was blown away by the wind, and then your mother came back ... The next morning, I found the broom standing upright, which means that someone straightened it before your mother went out last night or this morning. .....
Reasonable explanation ... If you are in poor health, you should have more rest. If you are afraid, you should go out at night and try to find someone to pick you up ... just relax and don't scare yourself.
By the way, I don't believe in ghosts ... I believe in Marx more. ..
