So many questions, so little time

When I was something like 8 years old, my parents took us around Lake Ontario in search of a cottage; a summer place to call our own. We were somewhere on the Canadian side, and I had NO idea where we were, but I remember staying for the night at some farm or house or some such place that was old and used. My grandparents, Tom and Alice Joseph slept beside my parents in one bed, while my parents slept in the other. I was on the floor next to them. I awoke in the middle of the night and watched a man walk back and forth across the floor in front of us; stopping for a moment to look at me, before leaving the room for good.
When I told my parents the next morning I was politely/laughingly told that no one but us was there that night.
I knew what I saw.
I've been crazy for the unexplained ever since.
