A childhood belief about around the house

In my old house we used to have floor boards, and one would always creek when I stepped on it, and I used to think that something was hidden under there, like old treasure or something, so one day I finally plucked up the courage to get out of bed at night, peel back the carpet and unscrew the floor board. I had a flash light so I could see underneath, and I heard what was like a ghost voice saying, go back to bed!!

So I quickly screwed on the floorboard and put the carpet back and ran to bed. I wouldn't walk on that part of the floor ever again. I always used to have to hold my breath for 5 seconds then run past other wise the ghost would come for me at night.

It's only recently that I found out, it was my dad telling me to go back to bed.
