Incredible day...

So I got invited over to a friend's house to help finish a project for school (as usual, I ended up doing most of the work, but that's not the point). I had never been to her house before, and we weren't sure where to go. Her cat led us there. Seriously, there's this big black and white cat sitting on the steps of her house. The weird part? It looked a lot like our cat that passed away 3 months ago. I mean, seriously, same all-black tail, same markings on its head, just a weird occurrence. My friends kept giving me odd looks because I did a double take everytime the cat would walk in the room. Every time, for just a second, I would think I was either a) going crazy, b) dreaming and about to wake up, or c) seeing ghosts. Lots of de ja vu in the house too, dunno why though.
