WHAT MONSTER DID THAT?!?

I was a very nervous and anxious child.  Like, really bad.  Sometimes adulthood can be a real challenge.

 

When I was maybe 10 years old or so, this beer commercial (see below) featuring Elvira came on while I was watching TV with my dad.  At one point during the commercial (:14), Elvira says "It's like Deja Vu," and then there's a quick screen wipe, and she repeats herself.  For some reason this threw me into a panic, and I turned to my dad and asked frantically "WHAT MONSTER DID THAT?!?"  My dad, confused and annoyed, said something like "I don't know, it's just silliness!" (How my dad talks)

Couple of things here - I didn't understand what "deja vu" meant, and I presumed what had happened to Elvira was something supernatural, which I already had an illogical fear of. Second, in my frenzied panic I didn't know how to express my question, so I asked my dad what "monster" could have done that.  For the record, my dad would have no idea about the monster.
