This was the very first paranormal experience of my life time. It happened about 25 years ago when I was still at a pre-teen age.
I have been together with my grandfather, my grandmother and my aunt in their 70sqm apartment and it was quite late in the evening at about 9 or 10 PM something.
All of us were together in the living room watching TV, when I needed to go to toilet at some time.
So I left the living room, walked along the hallway which connects all the rooms of the flat (the living room, a bathroom, two bedrooms and the toilet) and entered the toilet which lies at the straight end of the hallway.
Afterwards when walking back, as usual I peeped into the two bedrooms when passing across. It's always been a little eerie for me (as a young child) to look into the dark rooms at night, but nevertheless I always was just curious to do so.
In the first room I saw the silhouette of my grandpa standing at the window with is torso resting on his elbows, silently watching the happenings outside the house - he always used to do this occasionally.
In the second bedroom (my sleeping room) there was nothing but darkness and the hallway light and the lights from the street were shining inside a little.
Now the scary part for me was; when I entered the living room again to join the family watching TV, all of them were present there; my aunt, my grandma AND my grandpa!
So the silhouette in the first bedroom had certainly not been my grandpa who has left the living room because he was bored by TV or something and I can definitely exclude the possibility of any imaginary trick played by the light sources or such, since every inch of that apartment - and the views inside the rooms when they were only dim lit - were most familiar to me.
So who was the person standing there at the window of my grand-parents' bedroom?!
Of course I did not dare to go back to check again because it gave me the creeps, but also I didn't care too much about it during the days afterwards.
It was not at all "scaring the s**t out of me", but it was definitely confusing and I never forgot that happening.
Now, when I think about this again many years later, I come to one strong conclusion about who this figure might have been;
Due to the fact that the whole situation was not frightening to me at all and that the image "being shown to me" was something that I was actually familiar with, I guess this must have been some "spirit" who was friendly (!) indeed (and most probably it might have been the "household-spirit" who remained there, as I found out/was told only years later).
He obviously only wanted to give me some sort of a hint like "hey, I am here too! Please be aware of my presence".
Remember, I have been at the age of around 7-8 years back then, so of course it would have been very easy to scare me; therefore I think (for a spirit) it was quite considerate to appear in a familiar apparition like this to a child - in addition, giving me the effect of actually realizing the whole happening only some time afterwards and in a very trustful surrounding (back in the living room) made the whole happening quite "convenient" to me!
As I mentioned above, there was a household spirit in that apartment, which I was told by my relatives only when I was a little older, at the age of about 15-18 or something.
After many "séances" and talks to him (years later and together with my family) we found out that he was indeed very friendly and also concerned about me. (which I will explain more detailed in further stories of mine)
Anyway, what do you think about that apparition at the window? Do you think my conclusions sound plausible?
I am eager to read your opinions!
