Read the whole thread from start to finish, was having a shit week and now feel soooo much better.
I have one from a few years back, when myself and my BFF were living in a pokey little flat (ie: a shithole). She was going out with some of her college friends and her brother who was staying the night with us, I had to go to work next day so I went to bed early.
The flat was oddly set up, there was a door in the middle of the wall connecting her room to mine, and the bathroom was in her room. There was a tiny hall beside my room and a sitting room/kitchen. So around 3am the brother wakes up, starts looking for the bathroom by feeling along the wall, accidentally opens the door between the bedrooms and tumbles arse over tit into my room, scaring the bejeezus out of me. He tells me in a long drunken slur "It's okay, go back to sleep..." and he goes back to the other room.
A few hours later, I get up for work and I find my friend asleep in the hall, curled up in the foetal position and using my coat as a blanket. I wake her up and tell her to go to my bed (the whole flat is freezing at the best of times, the hall was Baltic) and then I go to the kitchen and find five men asleep in various places in the sitting room.
One of them woke up and started talking to me while I was getting ready for work, and told me about how my cat had been perched on the sofa staring at him all night. Said cat has only one eye, no teeth and her tongue flops out sometimes, he said every time he woke up she'd moved closer until she was perched on his chest just staring him down. At that point I walked in and she went to me for food, and he realized he hadn't been dreaming.
Oh, and not quite related but in the same flat when we had friends over our other cat, who had a nervous bowel, went into the litter tray and had the loudest, smelliest dump right behind the sofa as our friends listened in horror.
