She was downstairs putting stuff away in the kitchen when she heard the door that leads to the garage close twice. The door is very heavy and makes a distinct noise from being opened and when you let the door go it closes shut loudly. She went to check the garage but she found nothing unusual my two dogs were in their beds and the door that leads outside was closed. The only one who was downstairs was my stepdad but he was already taking a shower and when she asked him he said that he hadn’t opened the door. She came upstairs to ask me but I was with my nephew and was nowhere near the garage door.
