Tom Savini (who has a massive bug phobia) mentioned in a book on effects that when one of the cockroaches touched him, he teleported across the room. Not really a joke - he has no memory of physically crossing the room.
Also, Richard's revenge. Being immobilized in sand while the tide gets closer and closer to you and ultimately covers you.
Harry threatening Richard is more scary in that sense too. Especially when he manages go through with it after his death.
