This story takes place when I was young, in the early 90's. I don't really know how long this happened for because I experienced this more than once.
I would be lying in my bed and look at the ceiling and see a face. It wouldn't just be a two-dimensional shape of a face, it would actually stick out a couple of inches to about the ears and it was always the same material of the ceiling which was obviously plaster, although the eyes did look like regular (organic) eyes. It would stare at me with big, wide eyes and talk but I could never hear what it was saying.
At one point during these experiences, I had too much of it and went to my sisters room and slept on her floor. After sleeping for some time I woke up and there it was again. I woke my sister up and asked her if she saw it too and she did. Now the both of us were freaked out so we went to our parent's room and slept in their bed with them with the face staring at us all night with wide eyes, silently mouthing out something we couldn't hear.
I don't remember if we asked our parents if they saw it too but now that I think about it, I think I taught myself to not look at the ceiling at night and do not to this day. The strange thing is that I'm almost completely sure that our house isn't haunted. That's the only experiences we had.
My parents built our house so we know nobody died in it and there has been no house built on this land previously. To this day I don't know what this was.
