If I remember it well it was the head of the wife of the police inspector ( ( I don't believe it's shown to the audience, only implied ).
This classic serial killer flick sure made an impression on me, when I first watched it age 15 or 16 at a birthday party.
Oh oke, I didn't expect that!! Sure I imagine, well I still don't manage to watch movies in these genres... I prefer a story in a box instead of someones head:))
I get that. I used to watch a lot of horror/ thrillers, back in the days. Horror was basically my favorite genre but that has changed, I have changed.
With all the 'horror' ( the news ) we are bombarded with, on a daily basis, I have to be selective what I watch to not get dragged into the drama and get depressed again.
Yes indeed, have to be very careful what to let into your head!
I even go as far as not looking at any news at all, I'll deal with it when I see it in front of me:)
