I'm not sure if this falls under the paranormal category but I couldn't explain what it was that happened so I'm posting it here.
About five or so years ago I was home alone because my family went to some gathering or something like that and I didn't really feel like going. They left around 7 PM or so but didn't get back until almost 11 PM. It was in the fall, slowly making its way into winter. And in the fall/ winter, the days are much shorter because the sun goes down much earlier like around 4:00 PM to 5:00 PM. I kept all the lights on in the house because I'm a big scaredy cat when I'm by myself and it's impossible to see without them on. The TV was off in the living room and I was in my room listening to music.
It was probably around 9 or 10 when I left my room. And my house is kind of weird the way it's set up. I wish I had a diagram to help better explain. Anyway, my room exits to the living room as soon as you step outside the door, to the left is where the living room connects into the kitchen, then its kitchen to dining room and in the dining room there's a staircase that goes to the second floor and there's the back door. Sorry for this long explanation.
So I left my room to go into the kitchen and I don't know what I was doing exactly, I think I was washing the dishes or something. And while doing that I got one of those feelings where you feel like someone is behind you or more like the feeling you get when you know someone is looking at you. I ignored it of course because I was home alone. Then I literally jumped when I heard my mom's voice yell, "What are you doing Josh?!" So I respond with, "You scared the hell out of me, I didn't know you were home" and I'm still washing the dishes so I haven't turned around yet. I figured maybe she had come in through the back door when I was in my room because one set of keys she has doesn't have a house key and sometimes she grabs the wrong set of keys and we typically leave the back door unlocked (yeah I know its a terrible idea to do that).
She didn't respond so I turned around to see no one standing there. I stopped what I was doing and called out to find out where she went. No such luck. I calmly made my way back into my room, locking the door behind me and calling my parents to see if they were home or not. Mom picks up, "Yeah we're almost home we'll be there in about 10-15 minutes" Conclusion: She was never there but her voice was.
So then a cluster of thoughts ran through my mind. "Who did I hear? Did I really hear it or was it just my imagination? Am I crazy? Is this some sort or message or warning?" I honestly didn't know what to think. It was a strange experience in my life and a friend of mine told me that the same thing happened to him once, so I don't really know what to think.
I don't think this was paranormal as my mom is alive so it obviously wasn't her "ghost" or anything like that. I'm a pretty firm believer in paranormal events or occurrences so I don't ever want to rule anything out. But if you want to give me your opinion of what you think it might be, then by all means do so.
