Real Life Ghost Stories

The First Experience

So the first experience I've ever had in our new house was actually a ghost cat. Just so you guys know, as you walk in the front door, there is a wall directly in front of you as you walk in, with two long hallways on either side. In the right hallway is a lounge room, at the end there's the staircase, and the hallway leads into the kitchen/dining room area. Then in the left hallway are two small bedrooms, a bathroom and a toilet room. And that's all you guys need to know for now.
Now, in one of the small bedrooms in the left hallway, there used to be a 'chill out' room. There was a tv, PS4, Wii console, DVD player, bean bags, a single bed, and a dresser full of games, movies, and more.
One day, I was laying on the bed on my phone, and I had YouTube videos playing on the tv as background noise. As I was laying there, I saw my cat go behind my tv, as he always does. But I didn't want him behind there because there is a lot of cords. So I got up to get him out, but there was nothing there. I was so confused, and as I went to sit back on the bed, my cat walked into the room and jumped onto my lap.
I know this is a short story, but it's the first ghost experience I've had.
After that, Billy (the ghost cat) really started to hang around my room a lot. She used to sit by my old school bag near my desk, before I moved my furniture around. Sometimes you'll see him/her walking through my room. She likes to cuddle with my sisters, cousins, or me. But most of all, I feel her walk across or over my body while I'm in bed. You can't actually tell the difference between Billy and my actual cat Charlie unless you try to pet the cat.
