So I'm home alone, playing on my phone when I hear footsteps on my stairs, I thought were my partner so I go and see what's taking him so long to get to our room. He's no where to be seen, I call his name and walk around the entire upstairs, before heading down the stairs, to which I hear panting and really heavy breathing getting closer to me from one of our spare rooms. It sounded like a dog or a pig or something panting? I get downstairs and still no partner and now I'm sat here bricking it because i think there's something in my house... anyone got another explanation to this? I have no Pets and I have rang my partner who promises he's not been home..
