This happened when I was about 10-11 years old in my bedroom. One night I suddenly woke up to a presence in my room. I immediately looked to my wall where there was a face on my wall. It was very clear and it's hard to describe; it wasn't a person it didn't look exactly like a person you would see on the street but I knew it was a ghost. I stared at it for around 20-30 seconds, absolutely petrified not knowing what to do then, I ran as fast as I could to my parents room. They woke up and I said to them "can I sleep here tonight?" I didn't want to tell them what had happened because even though I knew my parents had their many paranormal encounters, I felt like I just wanted to be away from what had happened and I didn't think they would believe me. Everyday I think about it and I often look at the wall very few minutes to check if there is a face on it.
My house was made in the 60s and nobody has died in it. The only accident on my street was when a boy drowned in the lake next to my house while trying to get a football. Once when I was alone in my house I was downstairs in my living room and I clearly heard the words "what do we have here" right in my ear. I have also seen a tall man in my conservatory walk and then disappear. But once maybe the creepiest thing that has happened to me in the house was when I was playing football in the garden I saw my mother stare at me through her bedroom window even though she went out for the day and I checked all over the house and no one was there. Please comment and tell me why you think the face wanted to make itself known.
Joking aside, it does sound like you had a rather curious bunch - they sound inquisitive more than anything else. You mentioned that your parents had many experiences - if any of them were in the home or even experiences that happened away from the home but during the time you all lived there - that might help us get a better picture of what may have been afoot.
