It all happened a few months ago when a friend came over. We where just hanging out on my room, doing regular stuff that guys our age do. When I let him out of the house, we went downstairs and when he was getting his shoes on we heard a voice coming from upstairs, from my bedroom, slightly high it was. It only said maybe one or two words or mumble something. I couldn't hear if it made any sense what I heard. He said that it must be my pc or something else. But I knew it wasn't.
It's especially the fact he heard it too what makes me in the first place think it was not something I imagined, but on the other hand makes me think that it wasn't anything psychic at all.
I thought it might be a something spiritual, but I'm very inexperienced for this matter so I'm not getting to any conclusion yet. I still sometimes think about it and today I just went here to clear some things up. I haven't had any kind of psychic encounter in my life before and your thoughts would explain a lot, I hope.
I'm not worried, because these things never happened ever since, or before, but I am a little curious as to what it could possibly be...
Maybe it's from a person that once died in this house?
