A childhood belief about fear of

This is actually my brother's fear due to a dream of his. He dreamed once that he was sitting between a toilet and a wall in an old bathroom of a house we (my family) used to live in. He said that he was just sitting there and nothing was going on, until the toilet suddenly began attacking him. It was eating him up, limb by limb, and he said that no one would help him even though there were people in the room. It was a few weeks until he dared sit on a toilet for more than a few minutes in fear that dreaded toilet-monster would make a comeback. Poor brother. :p
