Reminds me of another story where a lady came into the galley to advise me that the gentleman sitting beside her was trying to grope her.
When I went down to the seat to speak to the man I had to wake him. When I explained what he was doing he burst into tears and simply said he did not realise he was touching her but that he was having nightmares about a car accident he had been in a week earlier which killed his wife and it was probably why is arms were moving. We checked out the cargo manifest and sure enough his wife was travelling with us down below.
What really annoyed me was despite all the crew being satisfied with this story and generally feeling sorry for the guy as he was rather upset, the lady beside just rolled her eyes and made a comment to me that I would believe any cock and bull story.
Needless to say we moved him away to a more "comfortable" seat!
