I always hear doors opening in my house, certain peoples voices talking (but somewhat muffled), and nothing is ever actually there. I think I might be hearing things. I also hear various other noises in my house, like the microwave, the fridge being opened, when I'm home alone.
And sometimes, I swear to God, when I'm just chillin in my house I hear faint background music.
Is this normal at all? I'm assuming it's because of stress. I am used to having a lot of people over.
