All you people must have realized that we are not alone when we think we are. In fact there exist tens of unseen creatures in all of our houses (even right now, around you). It's not that these creatures ("ghosts") are only found in haunted places or in places where you spot them, but they are also around places where you don't sense them or see them. The reason you're thinking they are not there is that the "ghosts" of that place are simply not interested in bothering you.
So my story is about my "unseens" in my bedroom. This happened a couple of months ago. I am not scared of darkness or "ghosts" or even demons or anything. Every time I experience something it is more challenging than the previous one.
So that night I was ready to sleep. There was no night lamp in my room but there was a very dim light that enveloped the room, you can at least figure out the walls and furniture and if someone stood in the room he would appear like a dark shadow.
I was half way to falling asleep but then I was disturbed by some murmuring sound, some people talking to each other. I did not sit up or make a big move when I woke up. I simply opened my eyes slowly. There was nobody in the room but as I saw in the mirror of my dresser (the mirror is big enough to see your whole body if you stand in front of it), I saw two boys, one around 6-7 years and the other around 11-12 years of age. I did not get freaked out but I just tried to make sure that what I am seeing is true and that I am not dreaming. So I looked where they were standing, they were not there, but when I saw in the mirror I could see them.
I did this for about 4 to 5 times to be sure that these people were only seen in the mirror and at the same time I tried to listen to their conversation. They were talking a strange language. I tried to understand them but I couldn't. They were just simply standing there and talking to each other as someone would in their own house. It looked like the "elder brother" was making the younger one understand something.
After a while of me "spying on them" maybe they came to know that I was not sleeping anymore and they stopped talking and turned their heads towards me slowly and slowly faded out. I went back to sleep with no surprising expression on my face as this was not the first or one of the "few" incidents, things happen all the time.
