Richard, we never had all the strange things you did, but when we moved to Texas just before I turned 17, Dad bought a big old two story house in Plano. At night we frequently heard what sounded like someone walking up in the attic. Of course, we considered the possibility of squirrels or other rodents, but the sound was too heavy and too measured for that. We also checked to make sure no limbs on the trees could touch the house, and those sounds happened whether the wind was blowing or not. We never did find any reason for the sounds, but nothing was every bothered.
