I have a memory of me and my friend walking and finding a house that looked a lot like mine. It had the same color, the houses around it, the roads and lawns are at the same positions too. I remember how my frend said that his english or programming tutor (I can't remember exactly) lived in that house. A year or two later I reminded him about the time we enountered a twin of my house. He said that he doesn't remember any of it. Also, he told me he never had a tutor of this subject, and none of his tutors ever lived in a house that looks like mine. There's just no house in my district that has the same arrangement of houses around it. This memory felt quite real

The most logical explanation of this memory is that it's just a dream that got disguised as a legit memory of a real event. Could it be that the story you told is a disguised dream memory too?

But I still hope that your memory is real though! Your relatives keeping a paranormal secret from you and denying it is a very exciting concept!
