hmm...was it him? or was it not him?

My brother & sis-inlaw used to stay with us in my parents' house. Their room was located downstairs.
I remembered once she told me that someone (or something) resembling my dad, a shirtless man with round belly, disturbing her..tickling her feet with some feather-duster-looking thingy. But as she tried to look closer (she was stil half asleep, half awaken) she saw that "he" had chains on him. At that time, my brother was in the toilet taking a midnight pee. He felt a gush of strong wind pass by when he opened the toilet door...the "someone" who was disturbing sis-inlaw was gone...
hmm...can't be my dad "flying" off in such speed at his age....
hmmmmmmmmm......
